Models<\/h2>\n\n\n\n

<\/p>\n\n\n\n

This week was mostly spent making 47 unique models of utensils and crockery, and about 100 with the variations. The are split into 3 sets, each set sharing one 4K texture set (will be downscaled in the engine to 2K later). About 500 triangles on average per model, but some are given more than others depending on shape complexity and whether I want them in closeups or not. Here are some beauty shot renders below, rendered in Blender Cycles. (click on each image to expand it)<\/p>\n\n\n\n

Color variation with UV Offsets<\/h2>\n\n\n\n

I made a UV offset-based color palette feature in my master shader a long time ago, and this is the first time I’ve used it in practice. All these models use the same material, and all the variations use the same textures, and share the same UVs (mostly)<\/p>\n\n\n

In short : I multiplied the texture palette coordinates 1\/8th, so everything inside the 0-1 UV space now corresponds to 0-0.125 in the palette texture (white in this case). I multiplied that color with the original base color, but since it’s white it does nothing.
Now if I move the UV’s of a certain part of the model to the right by 1, the original base color will look identical, but now we’re “selecting” the dark purple color, so the base color is multiplied by that.
For the best results, the original base color has to be a shade of white (with dirt and scratches and all that)<\/p>\n\n\n\n

additionally, I used a mask texture when creating the textures, to further limit which parts of the model are affected by this color change. This allows me to only recolor a motif or parts of the model, excluding drawings, rust, exposed metal, and anything else I do not want recolored.<\/p>\n\n\n
