Hi! I think I do something wrong but after 3 days of suffering I could not find it out what. I'm new in MDX, I would like to convert some GoogleWarehouse object (collada) to 3ds to be able to tweak/optimise them in gmax. In the attachement you can find my object. I import the model and I immediately push the drawcall minimizer. All options are checked (Detect duplicat, Replace col. etc.) He says no. of dr. minimized from 12 to 11. 3 textures merged. Actualy he generates two dds file as an output. The content is similar only one of them is a little bit darker. Than I export it to a 3ds open it with gmax. The problem is that he is using in some cases the two new generated dds but mostly the original Collada textures. I do not understand bec. the collada textures are really not designed according the "power of 2". Everything is in the attachement. Could you please check what do I do wrong or what is the problem? Thank you in advance!
