Materials lose textures

Hey, everybody. I am asking for your help in solving my problem.

When I open my map, some textures fly off. But they are actually applied to my mesh. To fix this, I have to open the material every time. After that it is loaded. But it doesn’t always work that way. Sometimes you have to open any texture map as well. This solution gives a temporary effect and after restarting the project the textures disappear again. Sometimes all the objects become as if the world grid material was applied to them. There are many materials in my project and I spend a lot of time to open each of them.

It’s worth clarifying that when loading a location, the message log says there are no errors.

I use virtual textures on maps with base color. I tried converting to regular textures, but this also gives only a temporary solution until the next restart. Any hints on what direction to look for a solution would be appreciated.

  1. Missing materials
  2. This is what the trash garbage can material looks like in the content browser Снимок экрана 2023-11-16 165535
  3. I open the edit mode of this material and it loads the textures
  4. After that, the materials appear on the grid

i got the same problem on v5.3.2,applied RVT on my landscape.but it seems not the version problem,sometimes it works & sometimes it got the same issue.
I’m certain my hardware could running this…

Thank you for your response. Unfortunately, it does not solve the problem. And yes, you are right, this problem appeared after upgrading to version 5.3.2.

Hi. Today I started to study the problem with texture loss and this is what I found out: the problem is in the use of virtual textures. I turned off support for this technology in the project settings, recompiled the shaders completely and all materials started to be displayed.
But now another problem has appeared. The response time has doubled. That is, I lost optimization of materials on my scene. I need to either increase RAM or optimize textures in a less modern way.
I hope my comment will help you and others to create their masterpieces! =)
