I'm taking my crack now at modeling, starting with simple rocks in the Dragon's Keep remake table. What I can't figure out is how FP lights my models. The model is a rock I made (fairly simple 15 polygons) and I've UV mapped the texture of a rock texture that I found online. It looks good except when its in FP -- the lighting sucks :)

Its like there is no lighting from the top on the object.

I also just now noticed that I'm not getting any reflection. I using a Peg type with my custom model and texture. In FPM it has reflection model set to use the main model.

EDIT: Ok simple error on the reflection -- since I had the rock somewhere else on the table I had set the Surface value to be of the object it was resting on -- and then when I moved the rock to the main playfield I forgot to change that value. Simple human error

So any ideas on the lighting

Here is the link to the ms3d, fpm and texture files:

there is no texture support applied on this model, therefore the shading appear reverse on the normal. Slapping a texture on the back of an object isn't the end of it :)

there, I fixed it for ya.

Thanks Steve - what changes do you do to the model to give it "texture support"? I had done the UV mapping with the texture and then in FP assigned the texture to the object. Was there something in Milkshape or Softimage XSI that you had to do?

thanks!

To clarify what I did. (refer to image below)

I loaded up my ms3d object in Milkshape, selected the group, then on the materials tab I created a new material and loaded my image/texture.

I adjusted the texture using the Emissive button and selected white to give a brighter texture.

Lastly I used Assign to assign the texture to the object.

I was able to see the texture applied in the 3D view.

I also verified that my texture coordinates (UV) that I applied in Blender were still assigned in Milkshape by using the Window->"Texture Coordinate Editor" option.

But when I bring it into FP using the same texture my rock has really odd shadows/lighting and generally isn't as bright as Steve's example.

I'm missing something so if anyone has clues it would be helpful!

thanks,

Would really like to help you mark but I am no milkshape expert.
You could ask anything in XSI but to explain what you (or the program) do wrong...I am as clueless as you are.

Sorry :(

Ah no worries Steve! I can try XSI next and see how that goes. I'll also look more at your ms3d file in blender yo see if other information is being added that I'm not aware of. I'm primarily using Blender for my object creation and just Milkshape to get the object center point corrected for FP.

Steve - would you be able to describe in a few more details what you did in XSI

Where in XSI did you do the changes to apply the texture support? I've only noticed a change in ambient lighting to white on scene_material1 for Phong. But that doesn't seem related to texture support.

If you could provide a few more tips on what you did in XSI it would very much help me understand how to model and texture more.

Let me know!
thanks
