3DS Max Baking Globar Supersampler artifacts?

Pioldes

Hi, I've run into a problem that I run into from time to time, and it's really starting to bug me. You see, it seems to happen randomly, and once it does, I can't fix it, no matter how my scenes I reset or create a new Max, skylight, etc.

Basically, when I get the glitch, I cannot use the global supersampler anymore. It turns my Lighting pass (which I use for AO) into a dot-riddled mess.

See.

In the renderer viewport:

In the actual Lighting Map:

What gives?

Pioldes

Yes, still doing the same.

I used to get the very same spots but from baking with MR. Never found solution for it unfortunately. You should try to bake with MR if you are using the scanline now.

Same problem here, let me know if you found a solution

I've seen this issue before. Try merging those objects or importing them into a new scene to rebake.

Clean scene, Edit Mesh, Reset XForm, increase the settings, etc.

Unfortunate as it may be, Autodesk (at least to my last check) has left some bugs in MR in Max which takes forever to bake something, and when they do they leave behind a whole slew of messy bakes.

My suggestion is either get VRay or do a Basic Scanline bake, or export you models via SBM to XNormal to keep and bake out everything as if they were in a Max environment.

We had to use xNormal at work to get around this.

Yeah, this is a common bug. It can be fixed, but it's not entirely straight forward. What I usually do is toss a reset x-form modifier on everything, both lp and hp, then rebake. If it still doesn't work, importing the files into a new scene will fix it.

1. turn super sample maps, and map filtering off.
2. MR has scale issues, so try and just scale everything up.
3. Max has some ridiculous error, when you copy your low poly from your hi-poly. was your low poly copied from your hi-poly when you started or did you start with a new mesh?

if you upload the file i can give it a look. shouldn't be to hard to fix.

try putting a push modifier on the low poly, and use a tiny push amount. dont know why it works but this usually fixes this for me

Totally forgot about this one! The older versions of Max (not sure which version they fixed it from onwards) has this MR issues where the LP and HP cannot be touching or else each vertice from the LP will be black.

You can either do the push modifier thingy, or do the more complicated "hide high poly, but still bake with it during render time" method.
