I have a tree with particle leaves. The image has alpha transparency, but it exports to glb with opaque background on the leaves. What do I need to do to remedy this?
Edit: I think I see the problem. I should’ve run the alpha out to the alpha channel, not the color out to alpha. Let me try it the right way and I’ll post an update.
Edit 2: Yep, I ran alpha of my alpha image to alpha of the Principle, and it solved the issue.
Show us your shader nodes- the only shader that exports is Principled, so if you’re doing anything else, it’s not going to export right

That may or may not also explain why the color ramp isn’t working to change the color of the leaf png on export.
If you have an actual image for the alpha map then the color information is the alpha. You maye have to double check the possible restrictions for the glb format. I’m almost sure it only can handle simple image maps but not a colorramp and especially not the partical info…
Yes, you are definitely right. I realized that after a while, but the tutorial said to do it this way for some reason.
Not everything named tutorial actually is done by a proper tutor…
