@dyceus the watertank looks really good though I think there's some shading issues with the jar encasement that may want checking.Also the box trimsheet is awesome! Here's my progress with the water tank project up to now. Not sure what to do with it from here so if anyone has any changes or suggestions let me know! *snip*
1- Should I try to keep the number of UV islands as low as possible? 2- Should (almost) every <90º edge be a seam? 3- Should I organize the Uvs by making each part a block or should I prioritize occupying the most empty spaces of the map? Also, what should be the margin between the islands? I've seen that while some margins work with high res textures it breaks when zoomed out in engine, so I had to increase the margin. 4- When there is a curved UV island should I make it straight/retanguar? Like with the UV of the side part of a wheel cut in half. It makes the UVs look nicer and seems to save space but I start to get some stretching. 5- I am thinking about making a single UV map for the whole wagon, so in engine I will use a single material for it. Is that right?
