PAINTING DIRTY GLASS - Game Asset Texture (DETAILED TUTORIAL) -Maya-Substance Painter-Toolbag-UE4

This tutorial explains a few techniques of painting/texturing dirty, grimy glass in Substance Painter, and then I also show how to set the glass material up in Marmoset Toolbag and Unreal Engine 4.
This is a detailed tutorial, but if you want me to cover anything more specific then please comment.
To see how to set up lighting in Marmoset Toolbag, please check out this tutorial -

Why my good sir!! You had no idea how long have I being looking for this guide!! Thank you so much!!!!!

[@Shagun-bh5kv]

Wow, more than Substance Painter, I got hooked and realized power of Marmoset. That's is something

[@stephenforsyth7883]

Thank you so much for your videos they have been instrumental to me, there are precious few resources on youtube that cover intermediate to more advanced game art concepts.

[@RobotArmy3D]

That's great to hear, I'm glad it's of benefit! 🙂

[@lukasallenbaugh4728]

Thank you! This video is the best I can find for textured glass, thanks for all the variations, your'e an excellent teacher.

[@RobotArmy3D]

Glad it was helpful!

[@unclejesseppe7323]

another thing i suggest, use the grunge scratches in height and rough for more realistic worn type glass. you can also add in finger and hand prints for even more realism

[@donovanbaine8842]

way to go man i was waiting u to show something like that ....u r a mind reader

[@RobotArmy3D]

Thanks! There isn't really much on glass on youtube, I hope to add another video on how to set up a better shader in UE4 in future 👍

I would love to see a tutorial about improving the glass reflections and roughness. I'm not very happy with the look of my dirty glass in unreal straight out of substance painter

I normally export the opacity map as black and white (there are also grays but I mean as having the whole range from 0 to 1), and then in UE4 plug it into a lerp node so you can remap the Opacity min and Opacity max. hope it helps

[@Marcryzk1]

Can you please specify.. What are the steps? What am I connecting the lerp node to?

[@asr59]

@@Marcryzk1 lerp node has 3 inputs, A, B, and alpha. Connect the texture to the Alpha input (any of the R Go or B channel). Then create two scalar parameter, connect one to the input A and that will be Roughness min, and the other to B, Roughness max.

[@Marcryzk1]

@@asr59 So, the texture that I'm connecting to alpha is the opacity mask right? And then what do you set your opacity min and max to? And does all of that connect to the opacity input of the material

[@asr59]

@@Marcryzk1 min to 0 and max to 1 by default. Then in the material instance tweak the min value to play with how transparent you want the material to be (0 being completely transparent and therefore invisible)

[@Dexxter_slav]

Any idea how to export the alpha for Cut-out in marmoset? I exported alpha as gray channel but the cut out alpha simply does not work in marmoset. I made a plane under my model with hidden geometry but the painted areas don't get effected by the opacity map. I have a choice of fully visible or fully hidden..

[@rwstczz2035]

how would you export this to arnold in maya

[@yantingye1677]

thank you so mcuh,now I know why my glass material do not have roughness and metailc and normal node ，谢谢

[@yantingye1677]

hi,when the blend mode is transluent and lighting mode is surface forwardShading in my material,then I turn on oveerview mode，the roghness and metalic channel are both still black,This should mean that these two channels and maps do not work. The glass effect of UE4 cannot feel the delicacy of rough map and metal map, which is much worse than that of Substance Painter and Toolbag. Does UE4 glass not support rough mapping and metal mapping at all?

[@RobotArmy3D]

@@yantingye1677 I'm not sure about the issue you are having, but UE4 does support metalrough with glass, its with the metal that you can get more realistic looking glass, this image might help you a little tinyurl.com/UEGlass

[@Bulborb1]

Make sure your AORM map is not set to sRGB in its image properties inside of unreal engine.

How do I add an opacity map to the Unreal engine packed export textures, you said you will link in comments but I don't see that?

[@RobotArmy3D]

Sorry bud, its in my channel, opacity export.

[@yarosyari3516]

I use unified mesh. Masked for my part of the mesh for opacity. It's not "opacity" slot in the main material but "masked". One video said I can't reach 0.5 dirt value opacity effect by using masked, but "1" or zero only! I tried something like Dither parameter on the main mesh but it sucks. How to resolve the case of dirty part with opacity for the unified mesh?

[@arjunladdhad8792]

i dont have the sun fade mask can you tell me where can i download them

[@RobotArmy3D]

If you go here - substance3d.adobe.com/community-assets/ you can find all sorts to download for painter - but in the top right you can access the old site, there is a smart masks category to the left, sun fade is in there. It's a great resource for free assets.

[@kardinal1441]

hey ! Really cool videos, are you planning to make a discord ?

[@RobotArmy3D]

Eventually, maybe. I think my channel is still to small right now. Thanks!

[@r6scrubs126]

I'm a beginner with all this stuff and I'm bit confused by the marmoset toolbag bit. What was the point of importing everything into there? It didn't look like you ever exported it from there and if it was just to make a nice looking render of it, can't that be done in the 3D modelling software you started with (Maya/Blender) just with the new textures from substance painter applied?

[@RobotArmy3D]

Marmoset toolbag is just a very popular choice for rendering game assets for portfolio, it simulates the type of rendering from an engine and is really easy to use and tweak, it also has brilliant art tools now. But yeah, using something like ue4/5 would be just as effective if a little harder and more technical to get the same quality levels.

[@r6scrubs126]

@@RobotArmy3D ahh ok so it was just an optional extra rather than part of the workflow if you're going straight to UE4 for a game asset. Thanks

[@jefm32]

Why everyone hates iray inside painter so much? Its so powerful when you set it up properly.

[@RobotArmy3D]

its great for quick renders, the lack of lights is a pain. if you want anything more specific then you will need to use other software.

UE4 needs some Planar Reflections, couldnt gives any good reflections.

[@RobotArmy3D]

Yes, I need to look into making better flat surfacer glass and reflections - UE4 does support planar, you need to activate it, maybe take a look and see if you can use them to get a nice glass result -docs.unrealengine.com/4.27/en-US/BuildingWorlds/LightingAndShadows/PlanarReflections/

[@mustafanuroncel]

@@RobotArmy3D Yes, of course.

[@lllllllla-dv8lw]

May I ask why all the models become transparent after the material is applied, and the base color is also wrong, and some models disappear😭😭
