Hey guys,<br>
<br>
I was chatting on IRC #cycles today and they said that this was the place to<br>
go with bug reports? Sorry if I'm in the wrong place.<br>
<br>
You may know of these bugs already, but I thought I'd mention them just in<br>
case.<br>
<br>
*Bugs*<br>
<br>
1. In complex scenes, previewing the scene in GPU mode results in an<br>
overload and a black screen. However, if you click the layers one by one<br>
then it doesn't. Very bizarre. I made this short video to show you what I<br>
mean: <a rel="nofollow" target="_blank" href="http://www.screencast.com/t/RnwLcZxIFq2">http://www.screencast.com/t/RnwLcZxIFq2</a><br>
2. When using hair particles with DupliObjects, it will never render the<br>
emitter, only the particles. Even though 'Emitter' is enabled in the<br>
particle render options.<br>
3. Cycles only recognizes the 'Preview' value for modifiers. Eg. If you<br>
add a subsurf modifier with View: 1 and Render: 3. It will render the View<br>
value, not the Render value.<br>
4. Most HDR images seem to warp strangely when looking at the back side.<br>
Here's a screenshot: <a rel="nofollow" target="_blank" href="http://i.imgur.com/PYqdD.jpg">http://i.imgur.com/PYqdD.jpg</a><br>
5. Image textures don't work until you set vector to 'Generated'. Not a<br>
big one, but it might confuse new users.<br>
<br>
Thanks for your time.<br>
<br>
Cycles is gonna be HUGE! You're all doing a great job :)<br>
<br>

Are there any errors in the console?<br>

Added this to the bugs list.<br>

<br>
This should be fixed in latest svn since a few days.<br>

Cycles expects latlong maps, is that the format you used? See here for<br>
comparison of formats:<br>

<br>
Image textures use UV coordinates by default, unlike other textures<br>
which use Generated.<br>
<br>
Thanks,<br>
