Edge padding for game characters
Hey fellas, I was wondering about edge padding distance in Xnormal. If I am doing a 2k map, I heard it is recommended to keep the number at about 16. The issue is UV islands bleed onto each other pretty bad even at the distance of 8 and the normal map looks messy when using that number. Most normal maps I've seen here on… -
Re: Edge padding for game characters
Xnormal does add edge padding near the end of render. Guess I'll be baking with no padding and using PS filter from now on to avoid such issues in the future. I do change and combine my normal maps in PS but no, the ones you see were both rendered in one go in xnormal. When xnormal adds edge padding, it overlaps them… -
Re: Edge padding for game characters
I don't bake out any edge padding since the map is going to change during the process of texturing. Once I'm done with the texture i use the dialate filter that xnormal installs in PS and when I do that I just fill up any remaining space in between the islands cause why the fuck not? -
Re: Edge padding for game characters
Yeah kot I think that might be hapenening cause its doing edge padding at render time, but Im not sure. When using dialation it will automatically stop padding once it hits another border. And I was mostly talking about baking vertex colors for the diffuse with my comment. But you could have detail normal overlays or… -
Re: Edge padding for game characters
There can't be too much edge-padding, as Dylan Brady said, just take you're finished texture, use your UV shells as a mask, and dilate outwards as much as you can, that's really the best practice. Of course you need to have left enough space between your UV shells when unwrapping, or you'll have problems either way. -
Re: Edge padding for game characters
You mean the normal map, right? How exactly does it change during texturing? Reason for asking is because I'm new to all this. So in other words doing dilation in PS filter is no different from doing edge padding in Xnormal? Then the questions is why bother with dilating in PS since the normal map won't change? Well, at… -
Re: Edge padding for game characters
You edge pad so when your textures get mipmapped, you don't get colours bleeding in at the borders due to the interpolation. So depending on the resolution of your base texture, and how it's going to be mipped, you can decide your padding size. As an example, going from 2048->1024 you will be interpolating 4 pixels, so… -
Re: Edge padding for game characters
is that overlapping island a separate normalmap you are combining in photoshop? It shouldnt be overlapping like that if both those islands are being baked in one go in Xnormal. The dilation filter is useful to have in photoshop if you are going to change the normalmap in any way. -
Re: Edge padding for game characters
thats weird. i havent had xnormal paddings break in to a neighboring uv island. but yeah if you do dilation in photoshop with your normalmap layers combined in to one, it wont overlap either.
