Non-square textures on non-square faces Some parts of a shelving system I want to model (Balton B III for those who like chrome and steel ;-) are from sheet metal with perforated areas, like this shelf, for instance. My challenge is to get the hexagonal perforation pattern into SH3D. First, I made a texture with two quarter holes (see 1st image, yellow rectangle), repeatedly mirrored along u and v in blender. However, I could not persuade SH3D of the mirroring. Then I made a non mirroring texture (green rectangle), and had it repeated in SH3D. See the rendered lower picture. But: - Whichever image size I enter in the Texture Import Wizard - it would not let me tweak the aspect ratio, only the absolute size. The wizard enforces a numeric ratio equal to that of the source image, which cannot be square. - However, when applying the texture the tiles turn out square - no matter what numbers I have entered. Question 1: how can I make the texture keep its proportions? - I just can't go with square tiles as my pattern demands a certain tile aspect, otherwise the pattern axes are at weird angles. Making a pre-baked texture for the whole area is not an option, because I have to "perforate" many differently sized areas on a variety of parts with the same pattern, plus the final pattern will be 9 times as fine - requiring several hundred tiles. Question 2 (maybe another thread?): The upper and lower image use the same texture. When I change the base material's colour, in blender the entire part changes. How can I in SH3D as well keep the base colour of the material in the perforated part, i.e. ignore, or at least transform the texture's RGB values? Originally, the texture is an SVG. I can easily derive any useful kind of pixel image. If a potential helper wants to see the .sh3d .obj, .mtl, .png, .svg or anything else - which upload service would you recommend? - Anyway, I'd be grateful for any thought, cause I just want to do my home in SH3D for its excellent fitness for the purpose and ease of use. Forgive me if I was just too blind to see the obvious. (Newbie) ---------------------------------------- Cheers - Joe // |
