Hi Mirackle,

I’m going to need just a bit more information regarding the material you were using that caused the crash. Could you provide screenshots of the material and it’s settings?

It is simple material imported with static mesh from maya with fbx format.

Hello Mirackle,

I was unable to reproduce your issue as in I was able to import and edit your asset and materials without a crash. However, I did notice that your asset is 2 million triangles with 93 materials applied. This is not recommended for use for game development as you are probably running out of memory resulting in a crash.

I would highly recommend that you lower the poly count on your asset. Shoot for as low a number you can and still maintain quality (20,000 - 50,000 should be fine). Also you can achieve the look of your asset with a handful of materials and some 2k-4k textures this would be much better than 93 materials with a solid color as each material is another draw.

Hope that helps,
