Regarding Shader tree imports, there was a bug in Vue 7.x that was termed the "Hulk Effect" because skin textures used to come out green inside Vue, that was fixed in later versions, since then I have had no Shader tree problems in either Vue 8.4 or 8.5

That is the one reason where the OP needs to answer whether he has at least done the first steps I mentioned to solving his issue, he openly admits to being a noob so let's see if there are noob errors before we go down the road of confusing him with other stuff..
