Bake normal map from one plane to another in max?

EarthQuake

So I could have sworn I did something like this before, but it doesn't seem to be working now.

I have a tiling texture that I want to rotate 105 degrees, so I can't do simple channel flipping to get there. I created one plane with the texture applied and tiled 9 times so it covers a smaller plane. I want to bake that material with normal map down onto a new normal map for.

I've assigned a material in max to the rotated plane with my normal map, and that shows up when rendered etc but it doesn't seem to show up in RTT. Is there something special I need to do to do this?

Is it even possible?

My first thought is just to convert normal map to heightmap, rotate and edit that in photoshop, and then convert heightmap to normal map.

You need to create a new plane and use the cage. You can't rebake an object normal map on itself afaik.
meh ok re-read and that's what you've done right ? Should work.
Yeah got it workin

So normal bump at 100 on the big plane
projection on the little., bake normal map
Check your uv's

I think i have wrong axis but that's just the normal bump to tweak.
Also you might want to push the little plane under to avoid artefacts.

Also i thought we had some photoshop actions to do so.

Make it tiling beforehand and use: http://www.polycount.com/forum/showpost.php?p=965355&postcount=25 maybe?

I think you could use the normalTexMap shader for this. http://www.scriptspot.com/3ds-max/scripts/normaltexmap. Just assign your existing normal map as usual with the diffuse set to normalTexMap and self illum set to 100%, apply to a plane, rotate and tile as desired. Then use your target plane to render with blowup and auto region selected turned on. you may need to set the target plane to be non-renderable.

I tried that but it breaks the tiling then. In my brain it should work but I guess it doesn't.

I ended up just doing 90 instead of 105, with help from fr00g1e's link.

Thanks for all the help!

You can bake one low to another with different UVs in the normal way (normal bump applied to the source of course)

Anyhow, glad you have it fixed!
