[MAYA] Creating a normal map with rounded corners of a low poly model without baking high poly

a_desentes · Feb 17 2025

I once used a script that transferred the selected edges and maya to photoshop, creating a ready-made normal map with rounded edges. Has anyone seen anything like this? (I tried Quixel Suite/nDo, but they didn't give me what I needed...)

you could break up the UV's into islands with the boundaries as the edges you want rounded.... export as obj load into this tool then using the element mask in photoshop ..... add a gaussian blur and use the nvidia plugin to convert to a normal map..... for example a simple box
uv elements (just each side)...

guassian @ about 4.... and nvidia tool @ 8

result....

you'd probably run into alignment/iffy seam problems on more complicated models and hand edit any wrap arounds (a cylinder for example) or make sure those islands go from exactly 0-1 in the direction of the wrap

I think I did it on the advice... I made a mask, used a blur filter, and used the nvidia tool

but the result turned out to be somehow strange (I converted dds to png, since the program does not see dds) p.s. in this part I am a noob...

try invert y on the nvidia tool

I inverted it on all axes and one separately, but it still turns out to be heresy

Can you show your normal map connection settings?

sorry dunno then... oh well

( your first normal map is the same as mine so it must be differences in Max and Maya (tangents and binomals) or the shader used)

it turned out to solve the problem!

it was only necessary to invert the y axis and change the values in use as

Thank you for your help!

by the way, have you used the edgeToPSSelection script?

I'm glad it worked

( as long as you don't look too closely

) no I haven't used edgeToPSSelection.
