texturing: is resizing good or bad
As some people might know, I in the process of texturing my model of a 2008 Mustang GT. What I have been trying to acomplish is to bake Hi poly mesh onto a Low poly mesh. In a previous thread, one other user had suggested using XNormal, which I have tried it. After trying different map sizes, I realize that lower map sizes, such as 512x512 as oppose to 2048z2048, does not just effect the rendering quality in Maya, but it also effects the normal direction around the uv borders. I thought I could try baking a 512x512 map because my main focus is to develop my models with a texturing size totaling no more than 512x512. In spite of this, I also unusally found that if I import a 2048x2048 normal map into Photoshop, and resize it to 512x512, I did not loose hardly any detail when mapping this normal map onto my low-poly mesh in Maya. Now I have heard from others in the past, that it is not recommended on resizing texture maps, since you will loose most of your details after resizing. However, in this case, did I just get lucky, that I did not loose hardly any detail after resizing the normal map, or am I wrong about others not recomending this method?
