Re: Bump Mapping and Camera Projections?

[Chris Marshall <chris(at)eclipsecreative.co.uk>]

Ahem, yes ok that might have been me! Sorry.
But my frustration was aimed more at your rather casual reply to a very important issue and , as you stated, sad state of XSI's bump mapping. It has had me in very deep trouble on more than one occasion, and in my opinion, should be fixed, or at least Zbump should be implemented and supported by Soft.

I fully realise it was a personal opinion you posted, and I certainly wouldn't want to stop anyone from doing that in future.

I've already said in a previous thread that I think bump mapping in XSI is a sad state of affairs and outline how it could be fixed *properly* but it would cost some development effort. That personal opinion got latched on as some kind of an official statement from Soft and so I'm not walking into that particular bear trap again.

Ok, now how do you make it work using a texture generator node? Or for a 3rd
party shader that doesn't have that 'enable bump' toggle on it?

Crimminy biscuits, Chris. Having a bad week?

These threads on bump mapping is like my wife asking whether I think
her bum looks bigger in trousers X. It's a lose-lose situation. There
is no right answer.

Anyway.

Get a bumpmap_generator node. Plug your texture map into it. Plug it
into the Bump port on the material. Enable "projection method for bump
basis". Create a camera projection for it.

That wasn't so hard now was it?

I'd stay away from using the bump mapping features of the individual
nodes and try to stick with the bump port on the materials. I have a
voodoo doll of the individual who suggested the bump map settings
should be on every single texture node. You practically can't see the
doll now for all the needles.

Bah, bump mapping through image nodes is such an ugly thing to do.
Btw, you don't plug your image node directly into a bump input, do
you? That would give plain wrong results...
      

I'm sure Soft support could help on this one! Specifically Halfdan,
maybe?
