Mix material with luminous in Ospray.

Glib — Thu, 22 Dec 2022 15:25:07 GMT

Hi,

I am trying to apply a mask to a luminous material in ospray, to simulate a multisector lamp. I did try using the "map_" prefix on "color" and "intensity" parameters without any effect. So I am trying to build a mix material by combining two luminous materials. The mix material works flawlessly when I use standard materials, I can see them being mixed based on the texture assigned to "map_factor" parameter. However, when I plug a luminous material into the mix the renderer throws an access violation exception.

Here is a sample:

ospray::cpp::Material lum1("pathtracer", "luminous"); lum1.setParam("intensity", 1.0f); lum1.setParam("color", vec3f(0.0f, 1.0f, 0.0f)); lum1.commit(); ospray::cpp::Material lum2("pathtracer", "luminous"); lum2.setParam("intensity", 0.0f); lum2.setParam("color", vec3f(0.0f, 0.0f, 1.0f)); lum2.commit(); ospray::cpp::Material mix("pathtracer", "mix"); mix.setParam("factor", 0.5f); //mix.setParam("map_factor", mask_texture); mix.setParam("material1", lum1); mix.setParam("material2", lum2); mix.commit();

Any ideas on how to make a partially luminous material? like this:

Thank you
