lighting in octane

[Sdados]

Hello everyone! it's my first post here and first of all i would like to express the great opinion that im getting on this program day after day! im new to it but im already amazed by what i saw (and really close to buy it )

now the question.
I have watched all the video guides about the demo, but i couldn't find the answer there.

is it possibile in octane render, to have lights different from HDRI or sun light?
If i want to put a point light, or mesh light, or what ever it could be, is it possibile? if yes how? if no, is it going to be implemented in the future?

i import my scenes from blender.

Thank you in advance for any help!!

Hi,
right now in the commercial beta 2.3 v5 you can either use
hdri (+ mesh emitters) or
sun (+ mesh emitters)

hdri + sun in one render will be added, currently you have to mix two renders in photoshop (or other software) to get such an effect.

You create a mesh emitter by increasing the emit value of any diffuse material (in commercial version). Point lights are not possible, but you can make your objects very small, of course.

thanks for the answer! ok so right now in demo version is not possible to have light sources different from sun or HDRI. I still have to understand which features are not included in demo version but are present in full full, and which are not present at all.

However next week ill be back from poland and i can test octane on my desktop (right now im with a 8600m Gt on a dell laptop) and check how it works with 250gts 1gb... but im pretty sure ill grab the full version!

i catch the opportunity to ask... has the problem with cores used solved with fermi cards? i remember i red something about not fully used cores on fermi cards with octane and i was thinking to upgrade to a 470gtx... is it a good deal from a 250?

thanks again!

Yep.. the GTX460 is currently using 224 of the possible 336 cores available.Not sure about the other cards.Once they compile a version using Cuda 3.2 then hopefully this will be solved and the GTX460 will run at 100%.

i don't know much about the 250, but since the 470 has 3.5 times the number of cuda cores and a better architecture, it should be much faster.
if your mainboard has two pcie slots you might want to keep that 250 to use this card for display and the 470 for rendering. (to speed up the interface)

the problem with the number of cores only appears on gf104 or newer chips, so there's no problem on 470/480/465.
And the next version, which will probably be built with cuda 3.2, won't have this problem anyway.

good news... thanks for the hints! i should have a second pci-e slot so i will keep my 250 for phyisx and interface calculations!

thank you again guys!
