HDRI help

blenderage · July 1, 2003, 2:48am

Hi guys I have donloaded a HDRI probe and im using yablex as far as I know this is what you do to get HDRI

1.set up scene
2.click on HDRI background in yablex GUI
3.specifiy file name of light probe
4.reduce hemi light colour value to 0
5.export

in the bagisas render log it say no light, using background instead then it says background envHDRI doesnt exist. This i assume is beacuse the file is in the wrong place.

So my questions are these.

1.Where do I put my probe file.
2.have I missed something completly stupid out (probably)

by the way my probe is called building_probe.hdr and thats what i typed in the yableX GUI

Cheers

Personally I’d edit the XML by hand, but otherwise you must define the ‘texture dir’ stuff in table and place the probe there.

still not working though I defined the tex directory where both the hdr probe is and where my blend file is and it still says it doesnt exist.

Well,

then open the XML with your favorite text editor and have a look …

I was bothered by the fact that YableX prepended a ‘none/’ in front of the probe name if I haven’t defined the texture dir…

I loaded it up and everything seems normal, i dont know what i should change. I downloaded an example file (the on with the holes in the cube) put the hdr in the hdr folder he said to put it in and it came up with the same error background envhdri doesnt exist.

Am I doing the correct thing by putting the hemilights colours all on Zero (the tooltips seem to contradict them selves)

Sorry to sound like a dumbass but I want shiny things!

Search at the end

Something like



&lt;light type="hemilight" name="sky" power= "1.500000" samples = "256" use_QMC = "off"&gt;
&lt;/light&gt;

&lt;background type = "HDRI" name = "envhdri" exposure_adjust = "0"&gt;
	&lt;filename value = "Probe512.hdr" /&gt;
&lt;/background&gt;

&lt;render camera_name = "Camera" AA_passes = "2" AA_minsamples = "2" AA_pixelwidth = "1.500000" AA_threshold = "0.040000" 
	raydepth = "128" bias = "0.0300000" gamma = "1.000000" exposure = "0.000000" background_name="envhdri" &gt;
	&lt;outfile value="Martini.tga"/&gt;

verify that the “hemilight” has no color like in my sample

verify that the background is right, expecially the filename

verify that the camera has a matching background_name with the background

good luck
