Concept Art

A piece of concept art I did over the weekend. It's a paint over piece, the source for which can be seen below. The source was rendered in Mental Ray with the indirect lighting generated by my app.

More realtime tests

The street scene running in the realtime renderer. The diffuse and specular textures have all been thrown on really quickly.

... and some more random dynamic lights ...

Realtime tests

Thought I'd blow the dust off an old render engine I was working on to test the lightmaps I've been generating. The scene's pretty basic but the lightmap (1024^2) is working well I think. I'll post some more complex scenes soon.

The old engine was a light pre pass type renderer so here's the scene rendered with 64 dynamic point lights. I also baked an ambient occlusion map to help modulate the lighting.

Arrival

A slight change from the usual lightmap tool updates, thought I'd post some test renders for a personal project I've been developing. It's early days yet so for now I'll let the pictures do the talking :)

Mental Ray comparison

I've been meaning to compare lightmap render times with mental ray for quite a while so here are the results for a 1024^2 lightmap. An example of the test scene can be seen in this post.  Direct and indirect light were calculated but I've only shown indirect light below.

Max 2010 / Mental Ray: 28 minutes

Settings: 

Final Gather set to 'High' preset with 1 diffuse bounce.

Lanczos filtering with 1 / 16 samples.

Logarithmic exposure control

Lit with mental ray sun / sky system

My app: 1 minute 30 seconds

Settings: 

3 bounces (total of  roughly 9000 rays per sample point)

 Lit with 1 directional light and HDR environment probe.

System specs.
