hi poly strategy

[Laurent]

I like to have as many as possible 3d trees in the scene, in cinema I would exclude them and their materials from the gi to speed things up. any work flow advises in a vray scene?

[Tong]

Select All Trees (by filter or by small old plugin pnSelect) or by ctrl +F by name select, then right mouse click on any of they, and select VrayBridge Tags - Vray compositing.

It will be placed on all objects that your selected, then just disable (by default in right corner of screen) in properties of Compositing - Gi Visibility.

All objects, that you selected now not visible by GI.

You can do it, with already placed compositing tags, just select all they (compositing tag) with mouse and ctrl (select in choose order) or shift (select in line order), or even just with mouse select the area of the screen, and do the same - disable Gi Visibility for all together.

thanks Tong,
no need to disable gi in the material illumination tag?

[Tong]

where did you find in vray material gi settings? :shock:

[Laurent]

in the material attributes window, in the illumination tab.

Hi Laurent,
download the updated version 1.02, the illumination panel in the VrayMaterial is definitively gone.

Cheers
Daniele

Laurent,ülease update to 1.02

the illumination tab was a leftover from AR. it is removed in 1.02 as it doesnt make sense in vray.

cheers
stefan

[Laurent]

Thanks guys.

[Tong]

Laurent, I have questions.

Do you import scene with trees that already exists in ArchiCad or some other CAD program file?

or all workflow in Cinema4D?

[Laurent]

no, I place some trees from an xfrog collection. and some real lowpoly of my making.

[Tong]

thanks for the answer.

I just was thinking when your place in scene so many hi-poly trees, does Cinema in your workflow is slowing down? Yea, Cinema have dynamic change of view, many poly auto change to boxes and so on, but nevertheless, slow?

[Laurent]

No it isn't slow as long as the trees are excluded from the GI and the antialiasing kept to the minimum on all those leaves.
by the way, in cinema to deal with all these alphas one behind the others I had also to bring up the ray and shadow depth, nothing special to do in the vraybridge?
