So I’ve been recently working on a scene which had a section of grass. I didn’t like the texture I’d used for the base of the grass at all. I then added the open world demo grass and left it at that. I then decided to try and change the grass texture I used. I downloaded a free texture from Megascans (Quixel Grass Cut) and it was was an 8K texture, extreme I know, and I wanted to use these but scaled down. As I imported them and replaced the material instance of grass I made, it changed itself and several other textures to the default grid material. I tried to up the texture streaming pool size, did nothing. Restarted the engine, did nothing. I’ve removed the textures from the engine, replaced the grass material for the previous maps and restarted and it did nothing so I’m out of ideas or a solution. I’ll provide any other information if needed to help find a solution to this! I need to get this issue fixed ASAP! Thanks in advance!
The material editor is probably throwing an error in the stats section at the bottom. My guess is the sampler type for one of the textures you replaced doesn’t match the sampler type it was originally using.
Can you post a screen shot of the material editor?
This is the stats I’ve got in the Master Material. The materials that are affected by this issue all display in the material previewer but not in the view-port/game so I’m really not sure what’s going on. All the materials that are affected use the same master material which is this material.
UPDATE - I found a post (Materials not displaying correctly. - Rendering - Unreal Engine Forums) and followed the steps of changing the sample type and this didn’t do anything for me.
