Hello.
I’m trying an interior viz project to get my hands dirty with UE4. It’s my first real project using the engine. The issue is that I made a master material to cover most of my material needs. Now, some of the material intances are showing up the generic gray boxes instead of the texture maps.
In the first image, there should be four material instances visible. But only one of them is working (which is the first instance I made, it that matters).
The second image is of the master material. I dunno if there’s any point putting this here, since if one of the instances works, I doubt the problem is here.
The third image is two of the instances. The brick one works fine. The concrete one, which used to work, shows the generic gray boxes now.
Here is some more info that I think might point towards the answer.
- All the instances used to work fine, but I tried to add displacement functionality to the master (and displacement maps to the brick instance) and then noticed the issue. I removed the displacement functionalty from the master but the issue persists.
- Any new instances of the master have the same issue.
- I created a totally new super basic master material, created an instance of it and used the same maps that aren’t showing with the original material/instance and it works.
- At some point yesterday I briefly saw a warning about texture pool size but can’t get it to reappear. I searched this online and found some console commands that increase it but they made no difference. I should mention that I don’t really know much about what texture pool size is, to be honest. Most of the maps I’m using are 4K, so it’s a heavy load.
- I can still import materials directly from Quixel Bridge and they work fine.
- I tried re-importing the maps. They’re all there where they should be. I restarted the editor, no joy.
- There’s nothing in the message log that indicates a problem.
I’m really scratching my head here and help would be appreciated a lot!
