STATUS uvw xform in corona
« on: February 10, 2017, 03:06:26 PM »
Hi there,

I've purchased my corona license some time ago, but I haven't used it a lot because the uvw xform isn't supported with instancing on.
Is there more news in the mean time?
Or is there an alternative, to generate quick texture randomizations?

Thank you,
Pieter

Hi,

We've been in contact with Corona team regarding the UVW XForm Operator functionality within the Corona renderer, but unfortunately the implementation isn't currently possible.

Using the Corona Multi Texmap (or similar map as explained in the "Using Bitmap loaders and randomisers" tightly related article) with "adjusted" versions of the texture(s) might be an option.

Best regards,

DRuivo

Hi, apparently Corona's Beta Version 1.7 (Scheduled to come out in the next following days) supports already UVW Randomization (They have their own modifier in max to add this nice feature.
Can iToo make it work now inside Corona? This would be a game changer for me, as I am trying to get away from V-Ray as quickly as possible.

No, sorry. Although they told us about this modifier, it cannot be used for RailClone.

We need to modify UVW at render time and for instanced segments. Actually this is possible only in V-Ray.
Also in RC3, when segment mapping is enabled, UVW coordinates are not only modified but also generated from scratch at render time.
