Decoding an error message

Hi. First, I should mention that you have a very very old version of s4s. A lot has change since in the game itself, so it is best to install s4s beta instead

That said, polycount may be the reason you’re getting this message. When you flip normals, the polycount stays the same. You most likely did it with solidify or by duplicating and flipping the geometry, which is not a reasonable approach to it.

You’re suppose to just select everything, remove doubles and Mesh - Normals - Recalculate outside


Regardless, please provide the blend and the package

Totally just deleted this original post by accident, I'm so sorry, but here's my package and blend files:

www.mediafire.com/file/ea5frmy42ocx38x/MAMA_KURTA.package/file


www.mediafire.com/file/ymvjf3wl830gxjn/vina_vp_fin.blend/file before flipping, which works fine

www.mediafire.com/file/ugp8lx6qa9gr36u/vina_normals.blend/file after flipping, which gives me the error message. I think you're right that I'm doing it wrong, I've just been following a tutorial I found





and here's the error message again:

ah, "flipping normals" was a bit misleading term to describe what you wanted to do.
bad news is that, yes, it is caused by the polycount. The one-sided version is highpoly enough to crash the game for many people, doubling the polycount of it exceeded s4s's limit.

If youre making this mesh for yourself and your game can run it, you can use the version without inner geometry. If you plan on sharing it with others, the mesh has to be re-done.
You have to go in MD, undo the automatic retopology ( never use it, it makes everything worse), switch to quads, and raise the particle distance. If there is no fine details to preserve, there is no point in the pattern having dense topology. After that, you add inner side only in places where it is visible, everywhere else it serves no purpose

I assume that you plan on making certain parts transparent, right? if yes, very bad idea to do this as a beginner, just creates you more problems and makes it harder to learn the basics.
But anyway, all parts that need transparency must be put away from where the skin texture is, otherwise they will display it instead of nothing underneath the garment's texture.
If no, you have to delete all areas covered by the garments. No cloth on cloth, no cloth on body.

Another bad idea was to mix the skirt with leggins. Those two things are adapted differently (rigging, vertex paint colors, uv_1) and you would need to transfer all data to them separately.

Unrelated to the problem at hand, but you should not scale uvs individually unless difference in quality is acceptable. Buttons can be bigger, sleeves should not be smaller than the rest of the top, it will be noticeable

I did switch to quads in MD, so I'm not sure how that happened! Maybe I went back on it somehow and don't remember.

I'm actually trying to make an adjusted version of this character's outfit, so no transparency:



Thank you so much for the help! Looks like I have my work cut out for me lol
