I just got Blender 2.34 and Yafray 0.7 I am trying to get the awsome caustics to work by creating transparent objects. I know that you have to have a photon light, and a sun light (or other general lighting light) and taht the raytransparent spectral must be 0 but i can’t figure out how to get it to work! I have done everything like a template that does work - i got it to work in the template (creating my own meshes and assigning new materials) but when i start my own blend from scratch it doesn’t work! what could be wrong?
A tut, a link to a tut or a simple explanation would be great!
i tried to figure it out on my own and i narrowed my problem down to my material. You see i created my scene then created my glass materials with all of the same aspects as a test blend i downloaded. The result was this:
As you can see the image is okay but there is no transparency to it!
I then appended the material from the test blend (every thing looked the same aspect wise) and then i rendered it again and i got this (the result i wanted!) :
So the answer lyes in the materials somewhere and yet i can’t find it! My spec are:
RGB: .782,0,0
RayMir: .02
RayFres: 0
Depth: 2
IOR: 1.50
RayFres: 0
Depth: 6 (test was five but works either way)
I can’t find the problem anywhere! Oh never mind! lol! As i just looked down at the screen i noticed the alpha bar was to 0! that would make a huge difference! I have got to be one of the lamest morons!
So for anyone else who can’t get it check to see if your alpha is to 0!
anyone who wants to say “hey moron what were you thinking” can! i diserve it! %|
Well, i think main reason for no-one answering is you post title, no body really can guess what you want to ask, if they just browse titles.
but any way.
As far I have understood, in order to use caustics you need to use photons, so, after you press change renderer to Yafray, make a new lamp and go to lamp options, where there is ythis new lamp type, photons. turn that on.
add a lamp, make it photon light. set it so it’ll point to the rings, make the angle as small as possible ( to fit the rings) and render. don’t use to many photons you’ll smell the flowers roots before you’ll se any resault.
yes i understand the lighting issue and i had already set that up and like i said in my second post - it was a material error! thanks for the response anyway - maybe it helps someone who hasn’t gotten it right yet!
yes it was a stupid title wasn’t it?! i don’t know why i did that!
