Odd surface

[nakamichi]

Hi I tried the rendering on a model. This is the first result. There is some funny warping surface problem at the top. Not sure if it is a problem of my surface or is it the enviroment hdr map.

Any ideas?

All comments welcome!!

Did you use a bump map? If yes, don't use negativ values now (bug).

Or you mesh settings are to low.

it seems to be a meshing problem,

not sure...

Hi nakamichi

Just a thought but it's not a problem with the normals?? I had a similar problem:

I don't know if you've gotten a fix yet, but from here it defintely looks like a meshing problem. Before you render go to the mesh settings and change them. The default setting in rhino (jagger and faster) is set to 20 degrees which is a horrible mesh. Even the smoother preset is not to good for rendering, so go to custom mesh and set the angle to something at or less the 12 degrees and the aspect ratio to between 6 and 1. Make sure you don't go crazy with the mesh. Even your model is crazy anything more than about 4 degrees is just overkill. Also make sure that you just change the mesh when you render because working in rhino with that refined of a mesh is going to suck.

Hi all

Thanks for your reply... After changing some stats, there are still some warping problems. Here are my mesh settings. What do you all think?

That is definitely starting to look better. I would change the settings to 4-6 degrees and change the aspect ratio to 1. Also you can try unchecking refine mesh because it might give you a little bit more randomness in the mesh. If you want to see the mesh before you render you can actually mesh the object yourself. Just type mesh and then you'll get a dialog box which just has a slider. If you click on detailed control you will get the same options that you do in the render mesh settings. Go through and set everything how you want it then mesh. Now go to advanced display and click show mesh wires in shaded views and now the mesh should show up. Hope this helps

to me it looks more like a smoothing issue...

I generally use another mesh setting btw: all values at 0, except max. dist. edge to srf. Then play with the min and max edge length settings it your mesh becomes either too large locally or too fine locally.
