tomtm 3 Report post Posted August 5, 2015 There is a bug again if you import using voxeling, the imported object doesn't have the pivot in the center. We had this again before 4.5 release. Share this post Link to post Share on other sites
carrots 54 Report post Posted August 6, 2015 (edited) Ok OpenCl disappeared again from roll out. I get error message : "can't get the number of OpenCl platforms" as soon as I select the Occlusion tool. Im trying with the robot sample so its not because its too heavy file. Yesterday it worked(well,not always...but it was always visible in roll out) but today its not there anymore. I did not change anything from yesterday.(4.5.09) Hi! Please try this update/fix (for 3DCoat 4.5.09 x64 only): https://drive.google.com/open?id=0B2DibXAfdFRacVQxa21ET0pBNlE * Fixed black result problems; * Optimized videomemory for per-vertex AO mode; * OpenCL initialization use only latest dll from Khronos Group. (The results currently can be white if deficiency of videomemory, I will try to fix this problem soon.) Thanks for testing!

Taros 370 Report post Posted August 6, 2015 What file and where you dropped? I checked and on my tests all works as expected - there are much more items in D&D menu. Andrew, it is an old windows 8 bug. Please read the comments: http://3d-coat.com/mantis/view.php?id=1911 Share this post Link to post Share on other sites

Thanks for testing! still getting "can't get the number of OpenCl platforms" as soon as I select the Occlusion tool. Even with the Default Robot file.... I would like for more users with NVidia graphic cards to report on this. Maybe my graphic card is dying or somethin.... 2 days ago everything worked fine with the new driver.... The only thing I did is changing UI a bit...very strange. Finally,I dont think that makes the "entire" build unsafe as its only one feature in the whole program and even maybe releasing the build with this issue will provide more feedback from other users that may lead to solution...

wilson66 25 Report post Posted August 6, 2015 (edited) AO baking artifacts: When using the 'name correspondence' option in the baking menu, other objects in the scene should be ignored to avoid artifacts. Doesn't work with AO baking though. Above is the bake using name correspondence (clearly visible "shadows" from surrounding objects), below another bake of the same scene without that option but manually hidden surrounding objects. Or is this correct behavior/ only for normal maps? Edited August 6, 2015 by wilson66 Share this post Link to post Share on other sites

Doesn't work with AO baking though. Above is the bake using name correspondence (clearly visible "shadows" from surrounding objects), below another bake of the same scene without that option but manually hidden surrounding objects. Or is this correct behavior/ only for normal maps? I agree, all the work done on AO in the Paint Room should be mirrored to the BAKE menu in the Retopo Room, and it should be available for PPP w/ Displacement and MicroVertex as well. That way, the user can take advantage of the Sequential Texture Baking, using "Naming Correspondence." In the mean time, you can just skip the AO baking when merging objects into the Paint Room, and just do it all in the Paint Room. But it won't work with normal maps, you may say. Andrew changed that just before 4.5 was released. It now takes advantage of normal maps during AO baking. So, that is a pretty BIG feature, in my opinion.

ajz3d 786 Report post Posted August 6, 2015 (edited) Noise stays on General Clay even when Noise checkbox is unchecked. In order to disable the noise, one needs to bring down its sliders to zero first. To reproduce, select General Clay, enable Noise, increase its amplitude and tweak its scale, then finally disable the noise and start sculpting. The noise will remain enabled.

ajz3d 786 Report post Posted August 6, 2015 Self-intersection Detection (General Clay) creates holes (with Merge and Repel actions) and spikes (Repel action) in the mesh. Also, Repel makes a garbled mess out of the surface. Reproducible on a default sphere. Share this post Link to post Share on other sites

ajz3d 786 Report post Posted August 6, 2015 (edited) Noise tool: if Realtime Preview is on... after press apply the settings are applied twice I don't think it's a bug, because the checkbox says Apply Realtime, so it's applied immediately after you tweak any of the parameters. The noise remains editable until you close the options window or switch to other tool. Though I admit that it's confusing and I got fooled many times by this mode thinking it's just a preview. Anyway, the Apply button gets hidden now once you enable Apply Realtime. And speaking of Noise tool, sometimes it becomes non-undoable for no reason. It happened to me several times during the last hour. Edited August 6, 2015 by ajz3d Share this post Link to post Share on other sites

Grimm 47 Report post Posted August 6, 2015 I haven't had any issues with OpenCL on my GTX460 (although I run on Linux). From the error it definitely looks like a driver issue, as it looks like it can't find the OpenCL libs. Is there a way to specify which GPU to run on? I have two, so it would be nice to be able to choose my other one that I don't use for the displays. Share this post Link to post Share on other sites

Maybe you already tried this, but re-install the latest driver, and at the beginning of the install, choose CUSTOM. After you proceed, there should be a small checkbox at the bottom left with the text "CLEAN INSTALL." That removes the old completely and installs the new. Then see if you still get that error message in 3D Coat. 1 Share this post Link to post Share on other sites
Michaelgdrs 742 Report post Posted August 6, 2015 Greetings , one small request please that will serve all the community. Can you kindly post hot-fixes link and a small description at the first page like usual? Changes:3.08.2015 4.5.09- OpenCL tweaked to solve existing problems.- Started refactoring. And seems it leads to functionaliny tweaking as well. Uncluttering allowed to use "On plane" in surface tools. It is in "Flattern tool" that may be really uselul.
