[V4.5 BETA (experimental)]

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!

I still dont understand why previous driver would work with 4.5.07 and not 4.5.08...

Me too :/

REAL Ambient Occlusion, please

 

AO need more control

Strength

Distance

Attenuation

Samples

 

Ty !

Yes, I'm already developing a ray tracing method, which will have these options.

The structure of the program is not designed for this request ?

or would it be possible to use OpenCL ?

Layer opacity, and other layer options can not be easily converted to use OpenCL

Thank you for the fix/update. It works on my end now, and very fast. Great work. Quick question about OpenCL....the Opacity sliders (Color, Depth, Roughness, Metalness) in the layer panel have long been VERY, VERY, VERY slow and to the point of almost being unusable, This issue has been raised with Andrew on multiple occasions. My question is, would it be possible to use OpenCL to accelerate and improve the interactivity of these sliders?

This can be optimized by using OpenCL, but development will require a lot of time because the structure of the program is not designed for this. (for this reason it is not included in the plan.)

on the robot  it works ok and  pretty fast too.

But for my personnal projects I use it mostly in vertex paint mode, probably polycount is too high and Im asking too much out of it....

but it did perform better in 4.5.07 altough sometimes result layer was blank.Now I get mostly error messages....

Well, I try to optimize the use of video memory in the near future.

Maybe tomorrow I upload update.

Error message says "Can't get numbers of OpenCL platforms".

Thanks!

Please tell me what graphics card is installed on your computer and other system specifications?!

Tried it and no joy.

 

Hi, my name is Vladimir, I develop AO for 3DCoat.

 

Please download this update and unzip to installation folder, replacing all files and try select OpenCL again.

This update has fixed initialize OpenCL and added messages about the failures.

 

Thank you for testing the latest changes!

- Quality "unfortunately" the same like before. No improvements here. Gaps are calculated bright, why? (See screenshot)

This is the right result, the normals deployed to light
