philnolan3d Posted December 6, 2008 Report Share Posted December 6, 2008 Alpha 42 Spray / Thaw bug: Going iover the same spot repeatedly does very little at first, then suddenly does a lot. This only happens with CUDA turned off. Video: http://screencast.com/t/gTGBNzRWXU Edit: video seems to be sped up or something. I didn't move my pen that fast. Render bug: This is with or without CUDA so probably not related. Rendering is fine, but after hitting Esc. the camera position changes. Video: http://screencast.com/t/GdOAY28p Also if resolution is increased a couple of times, the model disappears after hitting Esc. The only way I could get it back is restarting the program.

Advanced Member GED Posted December 7, 2008 Advanced Member Report Share Posted December 7, 2008 I think Ive found a workaround to my last problem I posted here - switching cuda off has got my inverted brushes to be much more powerful and responsive but now I have the problem philnolan has shown in his first video when cuda is off. so my experience so fat is something like this so cuda on = good positive brush weak negative brush cuda off = wierd/lumpy positive brush good negative brush.

Contributor artman Posted December 12, 2008 Contributor Report Share Posted December 12, 2008 Alpha 42 whenever I use the flatten brush after a while some strange artifacts appear on my models. I cannot smooth or affect them in any ways. So I tought they were just display quirks from the graphic card (quadrofx 1700) so I didn't pay attention. But when I save my file those display quirks turn into real mesh artifacts. The thing is the further I sculpt (alternating airbrush and flatten) more often and biggers they become. I tried cuda on/off incremental render on/off GL and DX I didnlt want to download cuda for win32 so I've only worked with the 64bit versions so far If somebody think it can help I'll try 32bit instead here is another example showing how it turns into a mesh artifact when saving the file Quote Link to comment Share on other sites More sharing options...
Contributor artman Posted December 13, 2008 Contributor Report Share Posted December 13, 2008 I found a workaround to the bug I mentionned earlier (see previous post) I just need to use flaten along with another surface tool like "draw with pen" and I musn't use it along with the airbrush otherwise I get the artifacts . Draw with pen is as cool as the airbrush so I don't mind. Quote Link to comment Share on other sites More sharing options...

Contributor artman Posted December 19, 2008 Contributor Report Share Posted December 19, 2008 (ldzywsj: try checking the invert mirror box,it worked for me ) alpha 45 cuda "Substract from" in vox tree options doesn't work for me anymore. (worked fine in alpha 44 simple) edit:this problem occur only with OpenGl maybe related to card quadro fx1700 also the new export indvidual objects doesn't work for me either it exports empty .obj but the new export whole scene works fine.

philnolan3d Posted December 21, 2008 Report Share Posted December 21, 2008 Non-voxel bug, so this may be old. With most tools this issue has been reasonably resolved, but with the clone tool (regular painting mode) the tool goes right through any window that you're clicking on. Like for example if you move the Clone Tool options panel around you'll also be painting a line under where ever the panel goes. I'm guessing this kind of thing will go away when the new interface comes about, but I just wanted to make sure it was known. BTW I'm also noticing my CPU usage going way up to 70% on average, one of the cores is at around 95%. This happens whenever 3DC is on the screen. When I switch back here to Firefox it drops to about 24%. It's not even a very large object that I'm working on. 2 textures at 2048 each and the object is 1.48mil polys. But the performance is really slow. 3DC: Firefox: Quote Link to comment Share on other sites More sharing options...

The frame rate was able to drop to around 30fps when our mouse or pen is not moved. But this feature seems not working properly in the latest build, FPS always stay at the highest fps all the time.

Advanced Member wailingmonkey Posted December 22, 2008 Advanced Member Report Share Posted December 22, 2008 Maybe my old graphics card (7800go), but I get instant 'circle of' artifacts when using the 'move' brush. If the brush size is reduced, still get the artifacting, but seems like around the region of the old brush size. The artifacts will smooth down, but it's probably something that would suck if you'd detailed your model and just wanted to tweak a certain small area. (forgot to add, this is with Alpha 45 Simple version) Quote Link to comment Share on other sites More sharing options...

(forgot to add, this is with Alpha 45 Simple version) I've noticed the same thing with Move, at least I think this is what you're talking about, but also with any of the Surface tools. I've been meaning to bring it up but kept forgetting. I've seen it for a long time, maybe since the alpha first started. See here I pinch an area, then the surrounding area has kind of a rippled effect. You can smooth it but... This is hard to describe, as you smooth it more areas around that spot, which looked fine, start to appear rippled then they get smooth again. Hope this video helps: http://screencast.com/t/eltUVXWs Here's another bug. When you hit File > New it clears the scene, but the file name across the top is still the same as your old one. So I haven't tried this but I'm afraid if this happens and I hit Save, it will over write the other file I had open before. Quote Link to comment Share on other sites More sharing options...
Contributor artman Posted December 22, 2008 Contributor Report Share Posted December 22, 2008 alpha 46 1-now both extract skin and "substract from" work fine in both opengl and dx 2-"export this object" in the rmb menu of the voxtree still doesn't work it exports an empty .obj also I forgot to mention this bug but I got this in all alphas I've tested :whenever I delete a subobject the subobject disappear from the screen but when I export to .obj or press "to polygons" the deleted subobject is still there. The only way I've found to delete it is to use the rectangle cutter of the E panel. I need to do this each time I wanna delete a subobject . ...the sculpting feeling is great very solid now that I know good brush sequences Quote Link to comment Share on other sites More sharing options...

philnolan3d Posted December 23, 2008 Report Share Posted December 23, 2008 The voxel models seem to have bubbles, or pockets of air inside them. This probably isn't a huge problem, but it does add to the polygon count and has a few times messed up my model when I accidentally cut into one of these pockets. You can see them easily in wireframe mode, here's a video: http://screencast.com/t/SNFoxXyA Another thing: After using the Transform Whole Object tool for just a few seconds (maybe 30) the navigation becomes very sluggish. If I sculpt a few strokes it becomes smooth again Quote Link to comment Share on other sites More sharing options...

philnolan3d Posted December 24, 2008 Report Share Posted December 24, 2008 In 47 cuda is really messing up my model and it doesn't undo. Example: http://screencast.com/t/kmrwBKYDVX If I turn cuda off it works normally. I can fix the holes by turning it off then using Fill, turning the depth too 0, and brushing around the edges of the holes. Earlier cuda versions didn't do this.

Member zerebrush Posted December 24, 2008 Member Report Share Posted December 24, 2008 Hi, most certainly this post should be moved. Sorry, but I could not find another place to post my question, dealing not with any possible "bugs" within 3DCoat, but with the lack of some basic knowledge itself. Because I mostly like to know what I am doing/using, I looked up "Voxel" within the Wikipedia, and got this here: A voxel represents the sub-volume box with constant scalar/vector value inside which is equal to scalar/vector value of the corresponding grid/pixel of the original discrete representation of the volumetric data. The boundaries of a voxel are exactly in the middle between neighboring grids. Voxel data sets have a limited resolution, as precise data is only available at the center of each cell. Under the assumption that the voxel data is sampling a suitably band-limited signal, accurate reconstructions of data points in between the sampled voxels can be attained by low-pass filtering the data set. Visually acceptable approximations to this low pass filter can be attained by polynomial interpolation such as tri-linear or tri-cubic interpolation. Now, I am not afraid to confess, that the above lines did near to nothing to help me understand the nature of Voxels. Maybe I can get some digestable answers here? Thank you for reading!

philnolan3d Posted December 24, 2008 Report Share Posted December 24, 2008 If it helps the word voxel comes from "volumetric pixel", so it's a pixel with volume. Quote Link to comment Share on other sites More sharing options...
Contributor artman Posted December 24, 2008 Contributor Report Share Posted December 24, 2008 alpha 47 cuda(quadrofx 1700) transpose mode "select with pen" does nothing on a lot of my models.(no selection is made,but the two-redpoints drag line is there) (but strangely it works fine when used on the default sphere) in Gl version transpose mode "ring" doesn't show the selection gradient (ok in dx version) undos on transpose actions gives weird results ( like multiple undos) but still transpose is a lot of fun and very powerful Quote Link to comment Share on other sites More sharing options...
philnolan3d Posted December 24, 2008 Report Share Posted December 24, 2008 OK I installed the latest version of the cuda toolkit and that solved my problem from above. Edit to save posts: I am seeing the attached error message often when increasing resolution. After I click Retry everything continues as normal. I'll send the log to Andrew. Edit again: after typing that last edit I went back to 3DC and it gave me an instability error asking me to save my work because it was crashing. I saved, but the saved file was 0KB with nothing in it. Quote Link to comment Share on other sites More sharing options...
