I am making a mashup dress and I am at the final stage where you make a recolour of the final mesh. But when I try to export it, I get the above error. I have checked this file so many times. Would someone please be able to take a look and tell me what I have done wrong?

(I have no other files in my game except the original dress and recolour, the new mashup mesh and the faulty recolour.)

Can you uppload the new mesh file, too?

You'll need to do a "fix TGI" on either the Bottom_alpha or Bottom (whichever you added last) - those two currently have identical instances (possibly both on the TXTR and TXMT, closed down SimPE before my brain registered which one/s). The one you fix also needs to be added to the 3DIR (should be fine if you add it to the bottom, I think it fixes itself in new recolor files).

Here is the mesh, and I will do what you suggested. You are always so helpful, thanks!

So I re-imported the images for both bottom and bottom_alpha and clicked Fix TGI for both, but now it has unlinked from the mesh so I am doing it wrong. Can you tell me how to do it correctly please? I've never used Fix TGI before and obviously don't know how to.

Ok so I worked out what to do. I just clicked on the two latest TXTR files and clicked the Fix TGI, then NO COMMIT, save.

It's now working! THANK YOU.
