OPACITY (GLASS): SUBSTANCE PAINTER TO BLENDER

Here's a workflow for taking a model that was created and UV unwrapped in Blender into Substance Painter to add textures (in particular, opacity or glass) and then exporting the textures from Substance Painter and using them in Blender.
In Substance Painter:
1. Choosing pbr-metal-roughness-with-alpha-blending for the glass shader
2. Adding an opacity channel for the glass
3. Export settings to export the opacity map (starts around 8:00)
In Blender:
1. Node set-up for the opacity map
2. Changes to the glass material (ie. alpha blend, screen space reflections)

This was perfect, explained everything I needed clearly, nicely split up so I could skip over what I already knew, you didn't add in a bunch of unnecessary padding to make the video longer for no reason, thank you so much 💖

[@zerobio]

Hey Lau, I'm really happy that this video works for you. Thanks for letting me know.

[@GimmeSomeChicken]

Wow thanks man you're really helping me out a lot! I am 23 and currently starting to learn blender and 3d modelling to try to make a living out of this since my situation isn't the best here in my country and you are helping me a lot with your videos, It's always nice to have some person similar to a mentor in such things and you are really fitting in this role! Thanks again!!!

[@zerobio]

I'm so glad you are finding the videos on this channel helpful. Keep going and good luck to you!

If I wanna see my maps in blender, I must keep'em in same folder as added first time, is there a way to take scene to another place and have maps attached to the model as usually?

[@cybyr_]

Thanks for the video. I had one small issue, I had to invert the opacity.png I made for it to work. Is there a way to avoid doing this in the future? Thanks!

[@zerobio]

Sure thing! You may be able to save a preset of sorts but I'm not sure so that opacity channel is always there. Let me know if you do cause I may want to

[@papolone]

Hi, thanks for the tutorial sir! I have a question: with that shader I try to have a label layer (just painted into the same mesh, no with 2 meshes like yours) above the glass but the label take the same opacity of the glass, doesn't matter if the layer is separate... Do you notice that?

[@zerobio]

Yes, I have a solution for this but I won't be able explain it here for another couple of hours as I am busy with my kids. I will write you back as soon as I can.

[@zerobio]

Try this ... create an image the EXACT SAME SIZE as the one you want to stamp onto the glass, ie for a rectangular label. Make the background BLACK and the foreground (rectangular shape) WHITE. So you now have two images the same size, the WHITE SHAPE on black background and the LABEL graphic. Both should be SQUARE, ie. 1024x1024. Export as PNG. In SP, create your glass material with alpha blending and opacity channel. Add a PAINT LAYER above the glass. Import the image with white shape as an ALPHA and import the LABEL graphic as a TEXTURE. On the paint layer properties, drag the white shape alpha onto the ALPHA ZONE (you can see that in my screenshot) and drag the mushroom texture image onto the BASE COLOUR. Turn the OPACITY of the paint layer all the way UP TO 1 for no transparency and click/paint to add the decal. You can adjust the roughness, height, metallic as you wish before you stamp the decal down. The alpha provides a solid colour base behind the label but just remember to make them exactly the same size. If you need more explanation, write me at [e-mail] and I will help you out.

[@Tenchinu]

worked all the way until the very end :( the opacity came in inverted. where there was supposed to have opacity, it came out black, and for what was solid, it made it transparent. Any clue why?

[@zerobio]

Hmm, if you are working in blender, a couple things I can think of: can you check that your polys are facing outwards on the glass. If they are facing inwards, you should flip them. That nay be something. Did you choose open GL in substance painter when you begin to bring in the model? If u let it default to direct x that may cause a problem, at least it does with normals. Did you set up the material properties in blender correctly with alpha blend or alpha hashed? Final thing you could try is, in the node setup, place an invert node after the opacity image map and see if that helps. Hope you can get it to work. If not, please consider writing me at [e-mail] and attach a few screenshots of your node tree, your model with glass etc and we can try to solve it. Perhaps send your blend file, actually.

[@bodstor]

Hello! Cycles does not have these settings in the materials, what should I do? My opacity map doesn't work at all

[@zerobio]

I often use Eevee. There are other ways to get transparency to work in Cycles. If you just search for "opacity map in cycles" you should find something. If you can't get it to work in Cycles, let me know and I will help out.

[@bodstor]

thank you very much for the answer! I already found a solution, everything is fine now@@zerobio

[@helloiamjack]

@@bodstor What was your solution? Please share for others who are in the same position

[@bodstor]

@@helloiamjack If you work in Cycles, then the best option would be to connect the opacity texture to the alpha socket, and that’s it.

[@naeembabakheil]

nice.. di we unwarp in blender or directly export to substance painter ?

[@zerobio]

Thanks. I unwrapped this in Blender.

[@MrCans94]

Спасибо! 8:54 You have not selected OpenGL. I think this is a mistake?

[@zerobio]

As fsr as I know it only matters for normal maps which I don't often use

[@georgesirinidis6210]

May I ask a question here ? What If we had to write over the transparent surface a text that isnt transparent ? Or a logo ? I have tried and it works on Iray but In Blender (Cycles) the transparency channel seems to influence the solid letters (or logo) as well

My glass is looking fine in substance painter but when I plug to texture maps in blender the mesh turns to purple color, pls help me

[@zerobio]

Hang on and I will write later but make sure you connect the nodes in blender correctly, ie opacity.png and transparent node thru mix shader. Also make sure you have enabled alpha blend for material. You may want to try backface culling on the material too. Then see if that all works for you and let me know. Otherwise take a screenshot of your nodes and email me at [e-mail] so we can talk further. Don't give up, it will work.

[@Outmind01]

Yeah, this works for eevee, doing what you suggest here in Cycles just gives me a black texture since there's no alpha blend to select.

[@zerobio]

I tend to use eevee all the time so that's why I made this. Hope that's good for you. If not, I'm sure there are videos about glass in blender using the opacity map. Thanks.
