Hey every one. I have desided to do some testing, on recently new topic of vray and maxwell comparisons and etc. I want to say from the start that I am not making this post to bash vray or maxwell, as a professional I respect all renders and their developers. The reason for this test is to study multiple aspects of vray such as gamma correction, color transmittance and gi transmittance.
I've started by doing the most simple tests. I placed 3 spheres into a scene with white gi environment. The shaders are vray mat's and maxwell diffuse mat's the colors are identical in both maxwell and vray. In this first test my goal is to see the amount of color which is being sent out by vray's default gi and how it would behave after gamma correction.
In the first image I have corrected maxwells gamma to 1.0 which is what vray is by default. We can see that maxwells image is much darker but the colors are very close between vray and mx.
Next set of images I have reverted the gamma in maxwell to 2.2 default and in vray's color mapping using egz gamma calculator I have input 0.45 value for bright multiplier. We see that while in vray everything is lifted shadows, brights but the colors are close to maxwell. However in maxwell the shadows are preserved and the colors are not as washed out. In the close up we see color bleed from spheres to the plane. This is much accentuated when the gamma correction is not applied as you can see on image 1 of vray. However in maxwell no color bleed happens.
Both sets are rendered with ppt.
Second test is a more complicated one. I have taken a middle point, so one cannot say which is more correct, vray maxwell and so on. I have taken a photograph with a specific lighting condition and have replicated it in vray and maxwell. My objective is not to replicate the photograph 100
% but to examine the expected behavior from a photo and how vray and maxwell will perform.

Scene for testing. Need max 7 or greater.

By default vray has rendered a much darker scene, with settings of qmc 100/100
When lifted gamma to 2.2 we notice a great deal of information being lost. Shadows become bright along with highlites. I also noticed much greater color transmittance from the sphere to the floor. While there is none on the photo or maxwell. What I have noticed in maxwell is that while illumination wise it had done a better job, the shadows are also bright. Which is vrays situation works better.
More to come...

Speed is everything to me since it's just me trying to do it all by yesterday.
