Hard crashed yesterday and locked up my pc while painting a sculpt. Turned out that in documents/3DCoat/data/Undo there were over 35 GBs of files piled up leaving my with almost non HD space. I assumed to occurred over the course of the day while modeling. Similar thing happens in documents/3DCoat/UserPrefs/UserScenes with autosave files.

I've been using 3d-coat for a long time, and I have found it to be a persistent inconvenience that whenever I undo something, the tool that is selected changes. I suppose that the intent is to revert to the tool that was in use at the step you have stepped back to, but it never seems to really work this way, and it is not generally what I want to have happen. Most of the time when I click undo it is because I have made a brush-stroke with one tool that didn't look quite right, and I want to try again. Unfortunately, IMO, trying a brush-stroke a second time also usually involves re-selecting the tool that I was using. I only made a brief search, but I don't see other threads which mention this, so perhaps I'm alone in finding this undo tool-switch to be undesirable, but I thought I'd put it out there in case there are others who feel like me... I hope I've described the situation clearly!

Hi, I want to increase number of undo, but I can`t find were this settings located 3D Coat 4.8

Seems that with my latest model and latest 3Dcoat Im again suffering from undo artifacts that are really frustrating. Mostly these appear after a while when using rectangle tool and undo. Sometimes undo does not clear the whole of the last painted area and sometimes it partly undoes multiple undo levels at a time. In the picture I had drawn the large rectangle but tried to undo it and the undo brought up the right corner and if I undoed more it completely ignored that large rectangle area and just kept undoing/artifacting the area more.

Did anyone know how to add more" undo" history instances in 3d coat, i cant find any way Did anyone know if is it possible to do it like photoshop??? THANKS

There is a bug affecting every model I create. It's really inconsistent. Sometimes when I undo or smooth, or turn symmetry off, it corrupts my mesh and is irreparable. It basically causes he mesh to have zero width on some part of it. I can't even undo to reverse the changes and hope to god that I have saved a recent backup. See attachment to view what happens. Notice the top part of the model's head that looks like its see through and pixelated almost.

When I was working on my alien from the 2nd challenge, I noticed that upon reaching a certain point in vertex texturing, some operations resulted in serious hard disk thrashing, which kept interrupting user's input devices like mouse or tablet. I checked the resource monitor for some clues and found out that the disk thrashing came from 3D Coat's write operations performed by undo queue in %USERPROFILE%\3D-Coat-V4\Undo directory. While most of the undo files stored there weren't that big (a couple of megabytes at most), there were few over 2,5 GB. After further inspection it turned out that those files stored information returned by Paint layers context menu->Freeze Painted Pixels. The more information the layer held, the longer and more severe the thrashing was. Also, Freeze->Invert Freeze/Selection resulted in the same disk usage. My final sculpture oscillates around 50M polygons (I know it's a total overkill, but I wanted to keep sculpture's high resolution in case I needed it in voxel painting) and I understand that this is a lot of information to process, especially if a layer that I freeze has the most coverage when compared to other. What I don't understand though, is the fact that I still had 24GB of free random-access memory available and the whole Undo directory contained only about 7.5GBs of information, so it could easily fit into RAM with a big reserve still remaining. This would save a lot of my HDD's lifespan. I remember someone once asked for an option to customize 3D Coat's path. If implemented, this would allow people to direct the program to some cheap replaceable, high speed/low capacity SSD and store all of its queue/temp/config files there. This would be the solution to the problem described above, but unfortunately according to my knowledge it was never implemented. The other solution I can think of is to allow users to define the maximum amount of RAM which can store undo information. So it the queue would go there instead of directly sending the queue item to HDD.
