many questions ...texture and daylight

[Bertrand]

Hello everyone,

I use octane for a year and I am very satisfied, but there are two things I can not do.

1. put a texture environment and have the most sun with shadows, is this possible?

2. How does one adjust a texture exactly? If I take a picture on the wall and you have to put a texture on it. Via scale 1 and 2 can not only play on scale in x and y but not on the position! How is it done?

Thank you for your help.

1. All time needed option which is not available now....there are some workarounds . . .sun + enviroment + light passing trough glass (architectural renderings)
2. Adjust your textures in your modeling application....Thats the procedure and you can use plugin for continius connection between Octane and your modeling aplication.


i dont have time now to write you more but use search on forum and you will find your asnwers pronto !
In what aplication you model your models ?

Write your comp + software specs

thaks for your reply,

but i don't understand "sun + enviroment + light passing trough glass (architectural renderings)"

how do you do to put a texture envirronement with the sun ?

Hi Bertrand,
what necko77 tried to told you is that:
Sun+envirnoment it's not possible at the moment
Sun rays didn't pass through glass material (only tweaking with the opacity this can be done....often windows are "emulated" with a glossy material+faloff map in the opacity slot)
...both of these are "under construction" by Otoy's staff

Cheers, Paolo

Thanks you.

For the glass, I already understood the trick.

But i have another question : with an hdri picture for exemple a blue sky, all my scene is on blue; what's the setting to counter this ? And have of course a scene with a blue sky and white light ?

Do this:
render your scene with sun and alpha enabled, then mix in post your background.
This is not good if you have a boat on the sea, all metallic glossy parts have to reflect blue sky and clouds.
On the market there are beautiful hdrs from Hyperfocal that illuminate very well your scenes, unfortunately the sun shadow is not sharp.
You can create a dome and a disc (mesh emitter) for fake sky and sun

Look at my examples: with and without fake dome+fake sun

the first render has a 360° dome with an Hyperfocal texture, then I rigged a disc to a target point to simulate the sun. Both emitters need to be balanced well in power.
