I imported a large model from the game but some textures become soapy, but when I click on them they become clear and of high quality, everything is fine, but after a while they become soapy again, the problem is is that they are soapy in the render too.

Hello Agilar, Welcome to the Forums.

What happens if you open the texture and set the ‘Mip Gen Settings’ to “No Mipmaps” (If that doesn’t work try setting ‘Texture Group’ to “2D Pixels (Unfiltered)”)

My theory is that since the model is large, the system that reduces texture resolution when you are far away (Mip maps) is misbehaving.

Hey @AGILAR999

It’s been brought to my attention that you have not replied as to whether any of those suggestions worked.

Mastering pixels, the pipes and systems they flow through is interesting to me, so I’m happy to be here for you until a good result is achieved.

Hi @AGILAR999 This is a common issue, texture streaming is not enough for this scene.
Make sure you Maximize the value of texture streaming pool size about 5000, based upon your scene load.
Still it will soapy viewport which won’t comes in render.
