End of last year I spend again 2 month in Dublin at Screen Scene. In this time i worked on the last season of Black Sails. Over the time I worked on several bits of the production, including layout, texturing/shading touch ups and lighting of a few shots.
Just found this great post at the chaosgroup board concerning random colors per object.
Normally i used the vrayUserColor and user attributes to create random hue shifts (more infos here) but this solution sounds even better. need to check it out for myself. as far as i know its only working with the nighly build after the 20th january for now.
thats what yolov wrote: "Here's a quick example of how it works, along with a scene that I'm attaching: - add extra vray attributes to a samplerInfo node (this will expose additional outputs to the samplerInfo) - connect the samplerInfo.vrayRndomByID to a ramp's vCoord (if you're using a vRamp) OR uCoord (for a uRamp) | or both, if you intend to switch between ramp modes --> the ramp's position and color values will be the range of colors to be distributed to the objects --> plug the ramp into a shader and use the same shader on lots of objects"
for more, have a look at the thread.
After creating the 3D Scene with Models, Shader, Lights & Animation there is often just one thing missing, render elements. Most of them are working straight from Vray, but to create nice and more important, constant Multi Matte elements you have to assign a lot of ids to your objects by hand. To get rid of this painful task, I wrote this small tool set. With the help of this script, you can easily Assign IDs and create Vray Multi Mattes with just a few clicks.
“all” assigns IDs to all Shapes / Materials
“Selected” assigns IDs to selected Shapes / Materials
with “unique”, you can decide if you just want to assign one ID to the Objects/Materials or an unique ID for all Objects / Materials
“Create Multi Matte Element” will create Vray RenderElements for all IDs in the current Scene.
just Place the mel file in your script folder and run it with dr_MM or just add “dr_MM;” to the end of the file and run it straight from the Script Editor
the new version (1.3) has now two additional buttons to create the Multi Mattes for Mats and Objects seperatly. New file, old link
here we go with the first free download. a script for Maya and Vray to controll the Reflection Samples.
a lot of people know this problem, the deadline is near, the renderings are slow and the 2d-people are using the whole farm (because they are more important). so first step, reduce the rendertime. and the struggle to keep the balance between noise free and fast is always hard to find with vray. i mean, its odd that increasing some samples can speed up the whole render process. samples like the reflection samples. that’s why i wrote this small script. when i am setting up my materials, i am often just using the default samples and then tweak it for the final scene. so all this small script does is changing the amount of reflectionSamples for multiple vray Materials depending on the glossiness.
will post a small tutorial/ collection of informations about sampling in vray soon. stay alert
