How to exclude lightmix passes when saving?

[dean_dmoo]

Hi,

When saving passes all the lightmix passes get saved as well. We don't use these so just end up having to manually delete them every time.

Is there a check box or process to disable them also being saved when saving the other passes (reflection, diffuse, etc)?

Hi I am not sure I understand your case. Why would you want to add a light mix render element but do not want to save it after rendering is complete?

Hi,

We use it to do a final tuning of the lighting before saving the rgb / effects channel out. So the updated lighting gets saved in the rgb, but there is no need to have each light in the mix saved as an individual render pass.

Yes but if you delete your render elements these changes will be unique and impossible to match in case you need it some time later.
You could test these tweaks during preview and in the end you can transfer them to scene like this:


After you have transferred the lights settings to scene you can render your final image. You could also create a new version of your 3ds Max file with the new lighting.

Would indeed be nice to have a setting to not save lightmix. Ideally you could set this per light to avoid having to manually add light selects (which is how we do it now).

We use light mix interactively in the VFB. Then we apply the settings to the scene, but then we have to delete the lightmix before rendering, and re-add it if we want to do more tweaking. It really is a pain. A lot of the time we only need light selects for some of the many lights. So a per light save setting would be super helpful.

Need also for all of this to work seamlessly with Deadline, which presently has difficulty simply using LightMix rather than light selects. I think it’s because LightMix requires the VRay VFB to save at all. Ideally we could disable the VRay VFB (which works much better with deadline as far as auto file naming, etc.) and still have single LightMix element save whatever light select we choose (and only those, not every light), and this would work seamlessly with Deadline’s “strict” file naming..

Hi,

I think we might getting our wires crossed with regards to my question. I don't want to remove the lightmix in the framebuffer and there is no need to send it to scene to be re-rendered. All we want to know is if there is an option when saving out the passes (tif's, jpeg's, whatever) to deselect the lightmix light passes. See image, we always delete the red passes because we don't use them in post. (The actual lightmix setting is saved in an *.lightmix file if we edited the final image before saving out.)

So if there is an option we can turn on to not have to delete the 5-10 tif files per image that would be great.
