Hello All, from a modeling and game point of view.
Is it easier to start with low poly rigged models and increase details of the model later ? or
Is it easier to start with High poly models and decrease details of the model later ?
I have a 500polys character set or a 20 000 polys character set
in both case, they are already textured.
From my small experience with modelers, it is better to have a high-poly model, and then decrease its poly-count. The reason is that high-poly model has more details, and when you produce a low-poly version, you simply remove these details. While if you start with low-poly model, it doesn’t have all these details at all, so you have to create them. It is more difficult.
If you’re talking about for LOD, one big reason starting with the lowest lod might be bad is that your mesh is going to change in 3d space as you cut up the polys and move the new verts around, but the uvs will be pretty much the same if you want the lods to use the same texture space… for lower LODs you can get away with weird texture coordinates… but with the highest level, uv stretching will be very obvious.
If you actually meant for normal mapping… I always start with the the high poly version because I usually end up trying something out that might need some extra polys on low poly mesh… if I had a low poly mesh already done and uv mapped, I’d have to make changes to both for any major tweak I did…
Also… while there are programs/plugins that reduce detail (while usually not that well)… there isn’t really anything that is going to add detail the way you want automatically…
