bump map in Mia material?

[hoi]

just wondering if anybody can get a bump map on the mia material to work, I tried using a Maya 2d and 3d texture putting into the bump slot and using a bump2d and bump3d node with the outnormal plugging into the bump slot..n still got no bumps.
Any suggestion or advice will be appreicated...
Thanks :)

Guess the answer is here.. thanks

I tried this technique and it works fine in mental ray for maya.

However when I render it on 64bit standalone the bump is missing.

Would anyone know why?

[hoi]

hmm..maybe the standalone doesn't recognize the maya nodes, try hooking up shader network with the MR nodes instead of maya nodes..I don't have the standalone of MR, just a suggestion ..good luck..let me know how it turn out

I used the above technique of plugging the bump into the misss_set_normal which goes into the bump slot of the mia.

I wonder if it has anything to do with the misss_set_normal itself??

Try this
To add a bump map to the mia_material shader

1. Create the following nodes: mib_passthrough_bump_map, mib_texture_remap, and mib_bump_basis. You also need to create a texture vector, and it is recommended that you do so by creating the mib_texture_vector node.
2. Connect mib_passthrough_bump_map.message to mia_material.bump.
3. Connect mib_texture_vector.outValue to mib_texture_remap.input.
4. Connect mib_texture_remap.outValue to mib_passthrough_bump_map.coord.
5. Connect mib_bump_basis.u to mib_passthrough_bump_map.u and mib_bump_basis.v to mib_passthrough_bump_map.v.

The misss-method does not work for me at all, but the rather large and complicated mib_bump-method does work. The only problem is that I want to use the same 2d placement node as my diffuse-texture. Can't seem to find a way to connect these two.

Have you guys tried the bumpCombiner shader? It is a really powerful tool, you can find it in the shaders section on this site, as also a tutorial in the tuts section.

I know its an old thread but just like to point out that the longwinded method didn't work on my 64bit maya yet the Misss method is perfecto! thankyou :)

I'm not sure how to put phenomena together really and the manual seems a bit complex with it so I just export out the shader instead and bring that into the scene if I need another 'copy' of the shader :)

I use the block to misss_set_normal bump, bump slot of the MIA technology. I do not know whether misss_set_normal itself what to do?

The only problem is, I think my diffuse texture 2D placement node. Can not seem to find a way to connect the two.
