Bump Mapping (2)

I have an image for my character's bump map. I've tried to use the bump map generator in render tree. but it doesn't see what i want. How do I add the bump to my character using the image.

Hi HapZungLam,

In order to see the impact of the bump map on the object, you might have to place an Intensity node between the Bumpmap Generator node and the Phong's Bump input. You should build your Render Tree like this:

Hope this helps

woow, this is very complicated. Thank you very much.

Yeah I know, at first glance it looks scary. I am used to the SI3D environment, where the material and texturing processes are very straightforward.

But in fact, when you get used to it, it's simple.
All bump information is "vector"-type (the yellow lines and dots), wich is a different kind of parameters than the color (the red lines/dots). So to be able to connect everything together you have to go through conversions. The only reason I used the Vector2color and Color2vector nodes are to be able to place an Intensity node between the bumpmap and the phong.

The Render Tree allow many many types of connections, so you have a great creative control over the object's shading.

Once you get your hands on XSI 2.0 this will be a lot easier. When you have to connect different node types it inserts the conversion nodes for you.

Thanks for the info, Ed

As time passes I feel more and more desperate with my XSI-version-before-2....... :~(
