OK, so there's the Cornell Box renders, made with PRO RENDER. PJF kindly uploaded his version to this thread earlier ( post number 40 ). This is great, because it gives me a way to demonstrate to members, some of the problems that have been sorted. First of all, take a look at the image by PJF, where the bottom of objects meet the floor. You will notice an EXCESSIVE amount of ambience, due not only to the amount of ambience being used, but also to the intensity of the colours themselves. Please also note, that PJF pointed out that the image in question was brought about by a lot of tweaking. Now then, let's take a look at PRO-RENDER's version ( CORNELL BOX 1 ). The first thing you'll probably notice, is the sheer intensity of the colour. This is because I have made the single area light more intense than would normally be called for. I have done this for a VERY good reason, and here is that reason... If, in PJF's example, he were to increase the intensity of the light, the EXCESSIVE ambience problem displayed, would be even MORE amplified, and would result in a worse image, and PJF would probably need some strong form of medication to contain his sanity :-) ...however, please note that in the PRO-RENDER version ( CORNELL BOX 1 ), even though the light is much stronger, and the colours more intense, the problem of EXCESSIVE ambience has been sorted. Please also note, that this was managed WITHOUT having to tweak anything, and also, that the box LEAKAGE problem has been sorted :-) Moving on, CORNELL BOX 2 shows the same type of scene, again rendered with PRO-RENDER, only this time, without any lights. Also, the cube has been changed to a sphere to show how PRO-RENDER handles transparency, reflection, and refraction. Please note that every material used in the four images I have posted here, are PRO-RENDER specific, and will be included among many other PRO-RENDER specific materials when the package is released. Finally, if nothing else, the two Cornell Box images show how the PRO-RENDER method handles the extemes, going from a STRONG light, right down to NO light at all! Be back soon. Regards, Len.
