3) Textures and Materials - Create Your First VRChat World

[@iconoclass]

If you want help, please do the following: 1. If you have any errors, look at the console tab, hit clear and look up the red errors that still remain. 2. If you still have questions use the search bar to look them up in the VRChat Discord before asking (chances are someone already had the same question that you did) discord.com/invite/vrchat Or if your problem is with 3rd-party tools (like UdonSharp), then search/ask in other relevant Discord servers, such as the UdonSharp Discord discord.gg/Ub2n8ZA Sorry if this seems harsh, I just don't want to spend my time answering simple questions. Helping people learn these topics is often thankless work. Please respect those who are giving you help and make sure to thank them! They want you to learn and grow as an artist! Thanks, Icono

[@MaisieSqueak]

Bless you for talking this through stage by stage. I hope I remember everything going forward (especially all those compression texture presets) I just threw the roughness map in to the texture and called it good (my first texture was some simple carpet) It looked pretty good... Kinda... A little like those odd bumpy surfaces you see in FFXIV when the camera gets too close to the ground.

[@iconoclass]

Use presets for the textures so they import with the same settings!

[@iiizeroiii1636]

it would be a crying shame if this series didn't get more entries. cool vids man, thank you.

[@katiarepublic7057]

Your tutorials are getting me through my first VRChat world! You probably don't require credit, but I will definitely try and find a cute way to give you credit in my world for teaching me!

[@skaterkenta]

that's a sweet thought! have you published it yet?

[@katiarepublic7057]

@@skaterkenta Yeah! It's really not finished after all this time, though. My college classes ramped up and it got buried under other projects. I go back to it every now and then, though! It's "Shady House of Po Town" if you wanna check it out. The most recent thing I added was a custom pool table model that I had designed for class

[@SethWuffer]

Thank you very much for these tutorials. Not many around for VRChat worlds, let alone this in depth

[@justinbonnet195]

No filler and easy to follow. Great stuff.

[@ProtoPropski]

at 18:30 you sighed so hard my dude, had me dead, but I appreciate your help, subbed, and liked you made my day in two ways.

[@iconoclass]

I shoulda just taught this lesson using Mochie's shader. Oh well. I cover it in episode 9.

[@VantenPlayz]

that sigh got me to subscribe, definitely needed with something like this

[@AuroraAlchemy]

In case anyone is wondering how to use GIMP to add the roughness map to the color/albedo map, these are the steps i did and they seem to work well: 1. Open the color/albedo map in GIMP, then open the roughness map in GIMP as a separate project (not as a layer) 2. Go back to the color/albedo map and right click inside the layers box (bottom right), then click "add alpha channel". Now, when you click on the "channels" tab you should see 4 channels, R G B and A for alpha. 3. At the top menu bar click "Colors", then "Components" from the drop down menu, then "Decompose". A pop up should appear. Choose "RGBA" from the drop down menu in the pop up, then click "OK". 4. Now you should have a new project open for you where the main albedo map has been broken down into 3 layers, RGB, and a 4th layer for alpha that is just white. 5. Now navigate to the roughness map that is open as a separate project. Hit control + c to copy the entire thing (or edit and then copy from the menu at the top). Navigate back to the new project that has all the channels decomposed into those 4 layers in the layers window. Click on the alpha layer and hit control + v to paste. It will be a floating layer right above the alpha layer, hit the anchor icon at the bottom to anchor it to the alpha layer. Now, if you click on the eye icon next to the RGB layers to make them invisible, you should still see your roughness map like it's. If that isn't the case something went wrong. 6. With all layers visible (open eye icon next to each layer), go to the top menu and click "Colors", then "Components" again from the drop down, then "Compose". When the pop up window appears again make sure you pick RGBA from the drop down and hit "OK". Now another new project should appear. 7. In this new project window (titled rgba compose), if you navigate to the channels tab in the bottom right and make the alpha channel invisible, the albedo should appear like normal. If this doesn't happen something went wrong. 8. With all layers visible, go to "File", "export as", then choose a location and name for your exported file. 9.Drag it into Unity like any other texture, add it as your albedo map in standard mode, and choose "Albedo Alpha" in the "Source" window. It should now work! Or, at least this worked for me on the couple textures i did it with. If it doesn't seem to do anything you can invert the roughness map in GIMP before copy pasting it into the alpha channel ("Colors" then "Invert" from the drop down).

[@iconoclass]

If there isn't a metallic map for the material, then you can just convert the grayscale roughness map to the alpha channel and plug it into the metallic map slot. Why Unity doesn't natively support roughness maps is beyond me. I had a procedure like this in the rough draft for this episode but decided to cut it from the script. I would ultimately recommend most people use more advanced shaders such as Mochie standard, Silent Filamented, z3y's shader or orels' shader. Plenty of options.

[@AuroraAlchemy]

@@iconoclass Can i ask you a question about render pipelines? When I look at shaders in the asset store, I see a lot of them say URP only. Does VRC SDK care what render pipeline you use? Should I stick with the built-in render pipeline and just forget about the URP shaders?

[@iconoclass]

@@AuroraAlchemy VRChat only works with the built-in render pipeline

[@lxrdwander5031]

I am loving these tutorials man, such great work. Thank you!

[@camh3958]

Mah duuude! How do you know so much? Thanks for the tutorials!

[@nathanturner3039]

loving the tutorials man. I've never used unity before and watching your tutorials has taught me a whole lot. I'm looking forward to the next episode :)

[@cDogRage]

This is a great introduction to PBR :)

[@ToniR96]

wow ... I'm just watching these because the tutorials are so good and interesting and calming... but also maybe I will build a world haha :D

[@Miggymini]

Your voice is very pleasant to listen to!

[@MultiAnime4U]

I too am now looking forward to your next video.

[@DarkBandit141]

the android options isnt there for me which is sucky because i wanna be able to make it quest compatible because i have a quest headset and all my friend are quest users how do i fix that?

[@iconoclass]

watch episode 1 and set up unity correctly. or download the VCC on vrc's downloads page

[@DarkCookiesNom]

When I put the Normal map into the small box for normal map it goes to a jet black and when I click fix now it still doesn't change and stays that color or sometimes it doesn't show me the fix option at all. how do I fix that??

[@vixiliannebrightsun81]

First of all, wanted to say thanks so much for this tutorial series, I am already fairly familiar with unity and things involving materials and textures and whatnot but I still learned some useful stuff here! I do have a question though. i noticed that you used a reflection probe as opposed to setting the graphics mode from forward to deferred and adding screen space reflections to the post processing stack. I imagine this was for performance's sake, but does VRChat actually support deferred rendering and screen space reflections should the author of a map choose to use them? Does it also support unbaked dynamic lighting as well?

[@iconoclass]

VRChat does not support deferred rendering. No VR game to my knowledge uses deferred rendering. Screen space effects are not recommended in VR because they will appear slightly different in each eye since they are post processing effects. In addition the reflections would break and disappear should the user look away from the objects that are being reflected.

[@Alexis2andsoOn]

It's a bit difficult to adjust the right Maps and Albedos and Tiling to some materials you find on websites, because they either have multiple Maps (like GL and DX) options or lack an Occlusion or other parts explained in this tutorial. Is there maybe a general guide on what to put where when making new Materials?

[@iconoclass]

GL and DX normal maps are the inverse of each other. They will look the same as each other if you set the intensity of one of them to -1. GL is the one that is used for Unity iirc. Just use the one that looks correct. Some materials don't have AO maps, especially if they weren't designed for game engines. There are plenty of general guides on materials on the internet, google them. Also watch episode 9 of my series where I cover this more.

[@BloodernutGaming]

im not sure if i missed this or it wasnt explained but you have to right click and make a new material then drag that onto the shape you want to texture

[@MatthiasEuler]

Thanks for your awesome Playlist. What do I have to do when the Texture-Website doesn't mention any Dimension data?

[@iconoclass]

You gotta guess

[@Thawah]

THANK you so much for these tutorials

[@fraxomfire6657]

I build an entire map with the room in the center and when I tried to bake the lighting it just bakes continuously forever, anyone get that too?

[@iconoclass]

Depending on how big the map is lighting it entirely with baked lighting may not be a viable option. Try turning off "Contribute GI" in the static dropdown for the large gameobject, set the lightmapper to progressive GPU and try again

[@hdsavion]

I know you've been probably tired having to respond to comments from these month old videos, but is there a reason why VRWorld toolkit doesn't appear at the top? I've imported it and it's in my scenes but the tab is nowhere to be found

[@iconoclass]

check the console tab for errors, make sure your SDK is updated. For further questions go to the VRC Discord

[@Alexis2andsoOn]

How do I get this mesh to adjust for the Reflection Probe? When I click the buttons only the gizmo for the position disappears and thats it.

[@iconoclass]

If you opened up a second inspector window that's why. At the top reset the window to the default perspective. I covered how to do this in ep1

[@Alexis2andsoOn]

@@iconoclass Thanks, that solved that problem. Now I just need to figure out how to get rid of these two icons for the probe and post processing volume that werent there before.

[@iconoclass]

turn them off in the gizmos dropdown

Do you know if the Quest 2 support BPR textures? Does it support normal maps etc.?

[@iconoclass]

yes

[@Asylus]

After I set up post processing, my grid started showing through my assets

[@buramie]

Hey, after applying some textures, I wanted to see what it looked in vrc, but when I went to build and test, it just gave me an error saying that the scene-standaloneWindows64-WorldName.vrcw does not exist. I have been trying to fix this issue for hours now but can't seem to find a solution online. Any idea?

Check the console for errors. Hit clear and look for solutions to the red ones that still exist

I cant select Setup Post Processing, in that menu i can only select the Post Processing Guide. Does someone know why this happens? Thanks
