I created this simple model so I can learn how to light my scenes... I'm having a tough time getting the right settings in Maya. I tried out Mental Ray and I really like the global illum. and ray tracing stuff, but I don't understand why it applys a filter that blurs my images, and I can't seem to turn it off. So I tryed using Maya Software rendering which is fine, but some of my shadows are "splotchy", they're not properly faded. <sigh> Any insights would be great as well as any general C&C, thanks!

v-- this is Mental Ray Render with a little sharpening in Photoshop because the original is kinda blurry. Blurryness most noticable on the white coloured walling.

v-- this is Maya Software Render, no photoshop sharpening, but my some of my shadows are rendering all "dusty". Doesn't have as cool a feel as the Mental Ray render

v-- this is my wires, currently at 1456 Tri's. Wheelchair tires eating up alot, I'm trying to keep the sillouhette nice and round.

Looks good, akvan. Nice texturing and lighting, though I'm not quite sure why you have some of the polygons in the walls ending in the middle and the extra polygons aren't adding to the silhouette. You could cut down a few triangles by welding the verts in the middle to the ones at the bottom.

Keep it up, and show us more!

thanks. okay so I had the same talk with my brother about the extra verts. The reason why I added them there is because I've actually very slightly pushed/pulled them so that it's not a completely flat and straight wall. Originally I had it straight, and it looked very artificial to me, but now I'm thinking maybe its too subtle, OR maybe its done well enough that it looks real! or maybe I'm crazy, lol :) tommorow I'll make a copy of a welded wall and compare it side by side

Try having a look at the antialiasing settings in mental ray, maybe that's why it gets blurry. I like what you've got, makes me think of Silent Hill for some reason.

The ambience is great I think. It feels kinda creepy mystery behind that door.

IMO the upper part of walls could be darker though. Otherwise it seems to ruin a bit the mystic feeling ;)

Nice work anyways.

Thanks for the comments and views. Today, I went and bought a Mental ray book so hopefully will have a nice final render soon

The overall image blur is caused by the multi-pixel filtering in the render settings. Try using a different filter to sharpen it up.

The shadows are most likely because you're using depth map shadows. You could switch to raytraced shadows, or change the dmap resolution, filter size, or bias. Might take some tweaking to get the result you want. If you're already using raytraced shadows, then you either have the light radius too high or not enough shadow rays.

I wanted to post this up, this is what I ended up with after messing around with lights and mental ray options. I had to render out mental ray and final gather seperately... for some reason final gather kept producing weird lense flaring effects. So instead I just used the single final gather pass and blended it on a mental ray pass in photoshop which was much easier, but gives my final screen a subtle "grainy" stylish effect which I'm still not sure I like or not. all C&C welcome of course

Posting the old render to compare side by side..
