Hi guys, i have a question concerning light components in H13. I have the following case: I want a light that only contributes to direct diffuse illumination. According to the documentation it should be possible with the category syntax to do just that, however i cannot seem to get it working. Here is the use case: The candle on the table has no illumination. The illumination comes from a sphere light. The sphere light has indirect contribution turned off because of noise issues. However the sphere light still contributes to direct reflection, where only the pyro sim should contribute. I cannot seem to dissable everything but direct diffuse on the sphere light....
Hey everybody, I'm looking for a new computer and I'm now standing with a dilemma. Should I choose the Xeon 6-core 2.1ghz or a i7 with a higher clockspeed? The thing is, that if I choose to go with the Xeon, I'll choose a workstation motherboard, so that I can expand with 1 more CPU later on. Also what is the most important components for quick renders, and simulations? CPU,GPU or RAM? Thanks a bunch in advance! Cheers, Jonas Jørgensen
lyonel posted a topic in Lighting & RenderingHi there, A good friend of mine recommended me the forum, so here I am . I started to learn houdini a week ago, I'm specialized in rendering, and I have a couple of questions regarding mantra and some special settings. My first issue is that I cannot recreate the refraction effect that allow me to color my shadows. The light is going through a red transparent object, so the shadow projected from that object shoudn't be that dark, but less opaque and a bit redish. For those of you that are familiar with vray, the option in that renderer is called affect shadows, in the vray material refraction tab. The second weird thing I have is regarding the image planes that should allow me to render extra aov. I do understand the concept of "export components" assigned to all the image planes that get the component attribute. But what if you want to have, let's say for the direct lighting (per components) image plane, the diffuse component only, and for another image plane (indirect lighting per components for instance), you want diffuse reflect and refract ? If you put diffuse, reflect, refract in the export components, you will have diffuse, reflect and refract for all the image planes. I'm not sure I'm super clear in what I'm saying, so please let me know if that's not understandable. Thanks in advance for your help. I might come back with other questions later . Cheers ! Lyonel
