Image Sequence rule

Whenever I am going to use an image sequence. Remember the naming convention has to switch from imagetest_####.jpg to imagetest.####.jpg

For preview in texture map to work

supported file formats are
- iff
- tiff
- tga (32bit)

But previews take awhile and pushing the "use image sequence" button on and off forces a refresh.

Displacement Issues

It is late. Vray and displacement maps never work out the way I think they would and its always been a bitch. I am tired so ill just leave this link here first  and check it out another time.

Applying similar shader to Instances

Had this same issue 3 years ago. Just found this script.

1. Go to master of instances and switch to select faces.
2. Select faces to apply shader.
3. Run script using "select -r (expandSelection());".
4. Apply shader.

In-case the script ever goes down, backup here. This is from Janne Ojala. Thank you.

About:
A simple script that rxpand selection to each instance if only
one instace is selected
Usage:
select any number of faces on one object and run:
select -r (expandSelection())
or
sets -e -forceElement blinn1SG (expandSelectionToInstances());
to assign directly to shaders

Scanline for Compositing

Entered a discussion today about Scanline files for .EXR. Definitely, if a file is bucket rendered, it is about 3x-5x slower to be read in nuke. - articles were dated back in 2010 though.

But it seems that vray 2.0 this has been addressed as stated on their website. A compositor told me that compression type and storage type; though both have the word scanline in there as an option are two different things.

Questions - I saw a blog post taken from 3dmax, they do indeed have a compression and storage type setting which indicates my compositing friend is right.

But if so, then where are the correct settings in Maya Vray to have the files output as scanline and unrelated but what is the "Auto data window (multi-channel scanline files only) button for?

UV Mapping Pass in Vray for Nuke

Separate files will need to be created prior to final render. Turn off all linear workflow tricks and set the file to be 32bit.
