<div dir="ltr"><div><div><div><div><div>Hi Brecht,<br><br></div>as we are creating a lot VFX for the advertising industry and we're converting our projects slowly but steadily to Cycles we're now at a point that bothers me and my colleagues a lot: A proper shadow pass that includes HDR environment lights and mesh lights.<br>
<br></div>In our production work flow we're taking light probes on the set whenever we need to create cg elements afterwards, this way we match the lighting situation perfectly with the real world conditions. <br>When we compose those elements into the shot we're used to use the shadow (& AO) pass (in vray / mental ray) and were a bit surprised as we saw that we've got no possibility to mimic that behaviour with Cycles and our lighting requirements as mesh and environment lights are not considered in cycles shadow pass..<br>
<br>Today I asked DingTo on IRC and he told me that there is a way to
take mesh lights into account by deleting "ls.prim == PRIM_NONE
&& " in kernel_emission.h<br>That is already a big leap forward but does not help us on our light
probe (IBL) work flow...so the question is: Do you know that this is not
only a small missing feature but is really crucial for VFX work? I
talked with Sebastian too and he's also missing it very much - without this, many projects are very cumbersome to do atm.<br><br></div>I searched a bit and was led to the wiki page where you collect all todos and especially this:<br>
<ul><li> Option to include environment lighting in shadow pass.</li></ul><a href="http://wiki.blender.org/index.php/Dev:2.6/Source/Render/Cycles/ToDo">http://wiki.blender.org/index.php/Dev:2.6/Source/Render/Cycles/ToDo</a><br>
<br></div></div><div>I really don't want to bash here - just raise the awareness of this issue. It's not only a missing feature, it's really a show stopper for us.<br><br>Is that feature hard to implement? Is there any chance you could tackle this issue in a relatively short amount of time? Should I write Ton and beg for dev time? <br>
<br>If you'd like to talk just drop me a message @plasmasolutions or g+ and I'll be online in IRC...<br clear="all"></div><div><div><div><div><div><div><br></div><div>Many greetings, Thomas<br></div><div><br></div>
<div>P.S: I'm happy that I'm not the only one with this request but I still wonder why there are not many more? Is Blender rarely used in the VFX field? <a href="https://developer.blender.org/T34272">https://developer.blender.org/T34272</a><br>
