Light cache pre-filter samples: It controls the number of samples taken during. Next monday we will get a 64bit machine to try out to see if this solves all our problems. In computer graphics, it can be a time-consuming process to render. The only way I see is to render it irradiance map in pieces and merge it using the irradiance map viewer, but even the viewer sometimes crashes. Most of the time max crashes without any warning but sometimes I get a message that Vray can't allocate memory. using irradiance map would be much faster and flexible if only I could get it to work. I am at a complete loss here and have been forced to Quasi Monte Carlo render the whole thing on our render farm which seems to take about a weak and a half. GI environment checked on at 1.5 and a soft blue light, 2 vray plane lights in front to brighten up the model, also 32 subdivs each. samples Under indirect illumination I have Ambient occlusion checked on, 32 subdivs. Irradiance I use preset medium, 50sph subdvis and 20 interp. looking at the Vray message window I see that Max allocates about 2 extra Mb per frame and my animation is 2500 frames so memory is a problem, I use the 3Gig switch but this does not help. Primary Irradiance Map and secondary light cache for rendering. Rendering a 10kx10k image at say -3/-3 VRay will downsample (by half) the resolution 3 times then create the irradiance map, so it actually takes samples from a. When I follow guides on rendering animations with Vray, its recommended to use the irradiance map for primary bounces, and light cache for secondary. I am using a very low irradiance map setting, but still enough to give me decent quality. Image sampler - set to Adaptive QMC to save RAM Does anyone know what is wrong with my settings There are 3 spot lights. Using Dome light setting, the lights come from HDRI map as direct light, and all kinds of effects like shadows, reflection, etc will be apparent. This can be illustrated in test render sample (see image 2.0/ Setting 2.1.B and Setting 2.2.B).
Show samples When enabled, V-Ray displays the samples in the irradiance map as small dots in the scene. The shadow in Dome light+ HDRI setting appears to be smoother than Vray sun setting. Lower values make the detail-enhanced areas more noisy, but faster to render. leaf size: 0.005m, afaik should be increased if problems occur.įace/level coef: 3.0 afaik should be increased if problems occurĭynamic memory limit: ? have no idea what this does please help A value of 1.0 means that the same number of subdivs is used as for the regular irradiance map samples. Max tree depth: 30, afaik should be low if problems occur. I have a lot of problems calculating the irradiance map for a walk through animation, I have very low samples and have set the following parameters in the system dialog.
