Thank you very much zber2, you’re right. I had not used the option to paint with an image (since zbrush 4r6) and I had not seen that the spotlight radius was at zero.

Hello,
this has actually been happening on all 3 4R8 releases.
I loose the ability to move the tool in 3d space then any slider behaves erratically.
ZBRUSH crashes then any text entered anywhere is gobbledygook… and I have to restart my mac.
––––
Probably not a major concern to most, but the TimeLine-BPR-Passes unfortunately crashes 4R8 too:
throwing a really big spanner in my workflow.
OSX 10.12.06 with 32G memory.
I’m not sure which one of the coders for ZBrush thought it was a good idea to have the Dynamic brush setting PER brush but I’d really like an option to have it affect ALL brushes when it’s turned off. I, like many others, use multiple brushes per session and having to double click on the dynamic off and on switch PER brush is just such a hassle and a little disconcerting. I’ve often been zoomed in working on detail and switched brushes and all of a sudden my brush is no longer there and then I realize that the stupid dynamic has been reengaged for that brush. Please Please Please give us a permanent Preferences option to turn this off. I do NOT use this EVER and don’t want it plaguing me.
Thanks!

The best you are going to do right now is a script Marcus wrote to turn Dynamic Draw Size off /on for all brushes.
This is awesome. Thanks so much for the link! 
Has Control Shift A been removed for clearing a mask?
And if so, has it been reassigned to something else?
afaik by default Ctrl+Shift+A was always (and still is) “Grow all mesh portion” (i.e. if you have a subtool comprised of multiple meshes and you select only a portion of some of the meshes then doing Ctrl+Shift+A will show these entire meshes but not the entire subtool)
cheers
Thank you but…
Um…
I think I’m confused. 4R8 changed so much stuff I might just be brainfarting due to oversaturation.
What was (or is) the hotkey for clearing a mask?
As I remember it was the same as clearing a selection (meaning selections done to a single mesh using Control Shift, or Control Alt Shift).
But…
Maybe I’m not only wrong, but muscle memory is now wrong too.
This stuff has been habit for years, when it stopped working it was sort of noticeable.
the default is just Ctrl+Click+ drag Background
I’m not aware of another one in the default config.
When in doubt look here.
cheers
I was looking at that as a matter of fact, and wondering in my befuddlement if it said the same stuff as 4R7 and earlyer, but I think my assessment of brainfarting is correct.
Thank you for the help.
I’m going to go back to being daft and ditzy now.
Cheers!

After upgrading to to 4r8 P2, I still have the same problem…
Can you please allow rename and other typing in the box available for users like me who have set the button size of the interface below 46. I ha ve a cintiq the res is 1600x900, size between 38 and 42 is good, 46 is big 
.
And can you disable the jump at the top of the list of the subtool when you hit a subtool directly on the canvas with the alt clic, boring.
Really think to go back to 4r7
I don’t know if that was brought out before but in 4r7 I caould place a shortcut to different lcation in Lightbox folder.
Like in ZAlphas a shortcut for directory on different harddrive with where I store all my images.
Now lightbox sees a shortcut file, but after opening it - it’s epty.
Compared with zbrush4 r7, at ZBrush4 r8, the startup time becomes very long and can not be tolerated, even if you have entered the interface,it still have to wait for a while, I can not operate before pop up the lightbox.

You can disable LightBox:
Look in Preferences under LightBox and disable Open At Launch.
Also disabling the “homepage” thing can help a lot as well.
To do that open the HomePage thing (yah, I know) and click on the gear icon, then select “Show If News Updated”.
Basically the problem with the homepage thing seems to be that if you have a slow internet connection (which I do) it takes forever to load and prevents ZBrush from loading.

Thank you for your reply.
Home page I have closed.
Lightbox, I also closed, and now I find that these two factors are not affecting the startup time.
Hey. When exporting a model to the fbx format, I get an error
The problem is in one sabtool. If select it when exporting, the following message appears:
How fix it? 
When I use close hole(edge action) sometimes I can’t drag left/right to change the shape.
For example I can do it on a cube but can’t do it on a cylinder.
I set the interactive curvature on.
Much appreciate for the help.
I am somewhat new to the ZBrush world. But lately I have been having issues with getting ZBrush to sculpt on surfaces. Its like it isn’t recognizing my brushes.
I created a brush using bricks using the Insert Multimesh tool. And when I try to sculpt on any surface whether it is a cube, a plane, one of my bricks I used, it just rotates the object. I’m on the object when I am trying to sculpt, I checked the subdivisions, it is in edit mode, I have a brush and a type of stroke selected. But it sill just rotates the object and doesn’t sculpt.
Please help! This is severely impeding the project I am working on!! I need help! Thank you! :(
Hey Christina is it possible you have more then one subtool and have something small like a tooth turned on and are trying to sculpt on the body? Try holding alt and clicking on the object you want to sculpt or go into subtools and make sure it’s selected.
It’s also possible you have spotlight projection turned on. It will allow the move brush to work but not others. Although I don’t think it spins the sculpt it just didn’t effect the surface.
After doing a clean install on my PC, I downloaded the 4R8 installer from the download link, and attempted to install it. I’ve turned off the anti-virus and windows firewall during the whole process, and unfortunately, there was no activity after clicking the installer executable. I’ve attempted to install it on my mobile studio pro, and the installation completed with no problems. What do I need to do to get it working on my PC?
