Two problems - bumpy terrain and older video cards

Hey,

I am using the paging scene manager mostly for the deformable terrain capabilities for a class project. I'm running into two issues with it that I can't seem to find posts about in the forums or anything in the documentation.

1) It runs fine on my Geforce 6600GT but on my group member's systems (several of whom have intel integrated video) the terrain doesn't show up. Are there particular options in the config file which require a more advanced video card that I could turn off?

2) My terrain is ending up very bumpy. Like, the overall shape of the terrain is correct per the heightmap, but on a very small level there are bumps all over it, like my terrain has the measles or something. Consistent small bumps in teh geometry, so they arne't bump mapping or anything like that, and I haven't specified any sort of bumping if it even supports that feature.

Here is my config file, mostly just slightly modified from the example ones included. I appreciate any suggestions.

use shader which are not present at intel integrated video.

Thanks! My group members will greatly appreciate this.

Any ideas on the bumpiness?

can you provide a screenshot. Try with vertex normal off and check if "bumpiness" is still visible in wireframe mode

I think I found the problem.

I added the line:

MaxPixelError=10

And it seemed to fix the problem. Apparently it was tesselating way more triangles than I needed, and the image generated from our terrain mesh wasn't as continuous as it should have been or something?

seems so. did you generate a 16bits raw or png grayscale image ? 8bits is just not enough (256 against 65535)

Yep, apparently the guy who generated the map used 8 bits. That would be our problem.
