Re: [Bf-committers] node ior
It's been like that for years, same with the transmission settings as well. Last time I tried, there were other problems using refracting materials in node trees too - it doesn't really work properly and is better to just avoid avoid node materials for this purpose (or use another renderer :).

Re: [Bf-committers] node ior
Maybe it's possible to just move this setting globally to the shader tree and solve this hidden annoyance. I'm not asking to correctly mix different transparent shaders but at least unify it in the UI and shader tree Daniel Salazar 3Developer.com On Sat, Oct 15, 2011 at 1:35 AM, Matt Ebb m...@mke3.net wrote: It's been like that for years, same with the transmission settings as well.

Re: [Bf-committers] what is the license of Blender GLSL shaders?
Hi Skoti, That's an interesting viewpoint as well. What I read in the GNU FAQ would mean: Even when we conclude that shader exports from Blender are GPL itself, for as long they're not used too link against a program, you can freely use them. It becomes like 'data' that way. AFAIK you can also freely bundle gpl-ed components with non-gpl, for as long they're not acting as one single program. This might be the most elegant solution; I should seek advise from FSF on it though :) Googling for the issue doesn't give replies sofar... it even shows this thread on the first page! -Ton- Ton Roosendaal Blender Foundation t...@blender.orgwww.blender.org Blender Institute Entrepotdok 57A 1018AD Amsterdam The Netherlands On 14 Oct, 2011, at 1:07, skoti wrote: Your code is not linked with the shaders, so you do not have to share your code. You just pass the code to drivers, and there is compiled and sent to the graphics card. Code of your program is not connected with the shader, and only run it through the driver (which is allowed to run as separate programsfrom non-free (shaders is separate programs) http://www.gnu.org/licenses/gpl-faq.html#NFUseGPLPlugins). Just do not hide the code shaders and shader code, do not changecode after reading from a file. On Thu, Oct 13, 2011 at 19:48, Dalai Felinto wrote: Hi Ton, the shader files (gpu_shader_material.glsl and gpu_shader_vertex.glsl) have no license header on them. Thus my hope that they were not under the GPL. In fact most of the code snippets we have there are classic implementations. I don't think they can even be under specific license. I find strange to have GPL reinforced over them. First: there's no BF or BFL license... it's just GNU GPL v2 or later. I guess I was a bit outdated :p I was referring to this http://www.blender.org/BL/ Thanks, Dalai 2011/10/13 Tom Mletter...@gmail.com Ton, check with FSF, but I seriously doubt that a shader would be expressive, and hence is not copyrightable. A generated shader is even less likely to be viewed as expressive.

But if I use the command (added on rev. 40061): shader = gpu.export_shader(scene,material) Is the shader still GPL/BFL? The shader is made of snippets of Blender code, so I can see what lawyers may clam. And technically speaking a GLSL Shader is a program (compiles and run in the GPU). It would be really sad if this is the case though. Otherwise this could be used for external engines.

No GPU, Ubuntu 64. There are no proprietary drivers on my system.

Re: [Bf-committers] Call for another RC build
One, two more details you may find useful: 1) I recently did a fresh install of Ubuntu 11.04 Natty Narwhal after my Oneiric Ocelot headache. 2) I accidentally saved my user preferences in Cycles, which I soon discovered caused the blender trunk releases to segfault from missing nodes, so I resaved the User Preferences in a newer trunk build which solved the segfault. If it's the latter, it's probably unlikely to be triggered by someone else, and not a serious issue, but if it's the former, then we have a bigger problem.

Re: [Bf-committers] Call for another RC build
Hi, It's best to report such bugs in the tracker, easier to manage that way. Also, it's not possible you have no GPU, it's probably an intel integrated graphics card. What also matters is, did this happen in a previous release or is this a new issue? And how are you starting Blender, double clicking, enter, terminal command? Maybe it's something like, you're double clicking and the second click incorrectly ends up on the splash screen. Brecht.
