System Information
WIN7 / I7 3930 / 32gb Ram / Gtx 560 TI 2GB

Blender Version
Broken:2.70 7660218
worked 2.70 362b25b3

Short description of error

Issue 1: Since cycles Bake in master, I am required to first save the image externally, then bake, then save the image again, and then reload image to actually see the result. As far as I know, cycles bake should show image in editor, right after bake, no external saving required.
Issue 2: In 7660218 in won't even let me save the image externally, I get an error message, that I have screenshoted below.

I have provided a blend file, attempting to bake a normal map from multires. Just press bake.

It doesn't produce any result, and I can not even save externally.

thanks.

tip: use one bug report per issue ;)

You don't need to save the image externally before baking, only after.

Issue 2: Here it saves fine . Does that problem happen if you don't bake too? If so it's not related to baking and could/should be reported separately

It doesn't produce any result

Right, this seem to be the only bake related part of the report. If you change your image to be sRGB and uncheck "linear" this will work. In fact the same issue happens if the colorspace is 'non-color'.

I think I'm doing something wrong in write_internal_bake_pixels(), introduced when I addressed @Sergey's concerns regarding color management.

i thought they where related. apologies. I will report that separately.

yes I know you shouldn't need to save externally, but I do, otherwise I get no result in the image editor. This goes for all bake builds i've used on my machine since it was included in master.

I changed to srgb as your recommended on BA before, and I still have blank image.

Did the same thing in yesterdays build 362b25b3, had to save externally and reload, and I got this result, which is a lot different to yours.

@NGMAT you changed the color space to sRGB but forgot to uncheck the 'float' option. Anyways, it should be fixed now. If you still have troubles (related to that issue) let me know and I reopen the entry. Thanks for reporting ;)

Ah you where right!

ok so it wiil be set that way by default after this report now?

my bake still doesn't looks as yours though. this what it looks like after following all the advice.

separate issue?

I forgot, I also opened your mesh and set all faces to Shade Smooth ;)

No, not set by default, we will respect whatever the user was using. But now we show the result even when the user is not using sRGB with no float.

you shouldn't have to set it to shade smooth.

If you are working on a high detail at level 6 or something, smooth shading can actually ruin the details.

in the past i've not had to set it to shade smooth.

(I may have to confirm this amongst sculptors on BA, ignore for now)

thanks for clarification.

@NGMAT anyways let's agree that this is an unrelated issue :) if you think internally it should handle the normals differently please let us know, but I have a feeling that the map I baked is correct for when using lowpoly smooth faces, and yours is correct for flat faces. So it's all good.

yep, it was confirmed to me that your way is correct anyway, I was wrong..

thanks for fixing this bug.
