the instance obj node and the instance sop are two different things. the instance sop making use of packed primitives, which are easier to handle as using only the one instance shape in the instance obj..

see attached hipfile

 

Many Thanks for your help Sebastian !

A first class Transmission Model to replace the cheap Phong / Cone Model by default in the mantra shader.

GGX looks to now work in transmision mode but it is not use in the mantra shader.

The GGX transmission looks to only work with the fresnel mask which is annoying.

 

Getting this by default in the mantra shader would be cool :

Also the Principle Shader is the disney 2012 BSDF without Transmission and without SSS which is quite limitating.

Implement the new 2015 model would be great :

Being able to DELETE BY BOUNDING OBJ or BOUNDING VOLUME (Points Only would be OK) like you can do in the GROUP SOP, but just do it in one step in the DELETE SOP.

Just use an attrib wrangle sop, the code for that shouldnt be longer than two three lines and make a preset out of it.

This should work fine

vector uv;
int prim;

float dist = xyzdist(1,@P,prim,uv);

vector pos = primuv(1,"P",prim,uv);

vector N = primuv(1,"N",prim,uv);

vector closest = pos -@P;

float dot = dot(normalize(closest),normalize(N));



if(dot >= 0){
    removepoint(0,@ptnum);
    }

add "bgeogz" and "bgeosc" to the standard file types.  using the extension to identify file types is pretty common in pipelines so having formats with .'s in them is kind of annoying.  i know this can be added with the geo formats file, but that's a nuisance to maintain.

UV Box projection type.

 

We have Sphere, Cylinder and Toriod but no basic cube projection type.

This would be easier if it were under the UV Texture or UV Project node, and acted like maya's UV projection of a grid, rather than having a separate unique node with UV Unwrap.

More mapping options on the Environment Map feature of the Skylight. The help does not even tell us what kind of map goes in that slot? Is it equatorial, angular, spherical, cross-box? So add a drop down that supports all those mapping styles for the sky.

This was added today I believe, according to the journal
