Sculpt tools do not work at all
Closed, ArchivedPublicKNOWN ISSUE

Description

Hello Blender

This is my first post here.

My sculpt tools do not work at all. I do love those tools and I bought my mac book pro to work with Blender specifically. However, when I use the sculpt tools, Blender doesn't crash or anything, they just don't work at all, as if I had nothing selected. I've tried all the sculpt tools, grab, layer etc. None of them do anything to the object. This problem doesn't occur in windows which I used before.
I haven't come across any other similar problems.

I am running a 2.44 intel mac book pro. 4gb ram with the 8600M GT nvidia card.

Regards,
Chris

I forgot to say that I am using mac OS Tiger, not Leopard.

Sounds obvious, forgive me, but are you using a tablet ?Sculpt works best with a tablet (although sadly the pressure sensitivity in Blender's sculp mode is broken on the Mac - see my post above).

In older versions the only thing you could do with a mouse would be the grab mode, but I think you can use the mouse in 2.45

Thanks for responding Michael,
I'm using Blender 2.45 but it still doesn't work for either the mouse, or the graphic tablet.
Unfortunately, It[any tool in sculpt] still has absolutely no effect. I'm now working straight from the "The Essential Blender" book, working with a cube, so I know I'm not making a mistake from a practical point of view.
It seems that to fix this problem I'll have to get windows. *sigh*

could you try a current cvs build? We think it might be that the mouse on a mac was outputing as if it were a pen tablet with the value set to zero.

Chris: at least one other user has found this problem fixed in recent builds; could you try one of the builds from graphicall:

http://www.graphicall.org/builds/index.php

and report back if it's fixed?

This is an opengl related issue...

Chris: our official releases (get them from download.blender.org/release/) are reported to work fine for sculpting on macs... if your mbp doesn't work, you're most likely having a driver or configuration error in the system. Is there anything nonstandard there, something you installed or comfigured?

You could also try on other computers to check it?
Next issue then; how come your 10.4 install doesn't work? Interesting to fi

Ton,

actually there was a driver change on the OS X side and apparently lukep found what it was - some OpenGL setting related to backbuffering (BACK_STORE ??) was implicit previously and is now explicit - so it needs to be enabled as an explicit variable for current OS X.

This is a generic request to test your bug report and see if it is still an issue in 2.5alpha2 if so please let me know by making a comment in this report ie 'also in 2.5alpha2' and I will add it to the 2.5 bug list.

Hi guys,

Was reminded about this issue due to your recent post (was emailed a notification). Apologies for not replying much much sooner. I had completely forgot about this issue.

This issue is considered resolved from my point of view. I'm running the version 2.49b on the same laptop but the OS was changed from Tiger to Leopard. It is currently working fine and has been for a good few releases, Unfortunately I couldn't tell you which release it started working. (However, it may be due to the fact that I upgraded from OS X Tiger to Leopard back in 2008 soon after I made this bug report)

Thanks,
Chris
