how are you able to render HDRI together with Dalight?

I'm not :/
I first render a daylight image and then a hdr one and mix them together using Gimp playing with the alpha slider.

Effectivement, Enrico, je suis certain que ce sont tes magnifiques images qui on fait revenir le soleil aujord'hui !
J'aime beaucoup l'atmosphère de cette série, beaucoup plus 'optimiste' que ta précédente série (que j'ai aussi adorée !). Le soin apporté aux détails est, comme toujours, extraordinaire.

Excellent work!

Wonderful scene Enrico !

Didn't you encounter a problem with transparent shadows for trees leaves ?

I have just found that transparent shadows seem to be broken since Octane 1.11 !

Merci Thierry, j'espère que vous en avez bien profité, bonjour chez toi et à+;)

Thanks Roubal : Yes indeed I have a similar problem with leaks on the wall, I used a blender shrinked wrap mesh (probably like you) and noticed that I had a shadow under the whole surface. Didn't thought to a bug first and finally had to create a mesh covering all my wall to avoid that, but now you point it, it seems to be a bug and I hope this to be solved quickely, very annoying indeed.

Hello Sir! Great work. I really, really love what you do with octane render and Blender.

'All the vegetation is home made and generated with a script I developed in Python for Blender 2.49'

Any chance of getting that magic script from you ?? Please ?



Thanks

Thanks Cadvis,

Well, as said to other who also asked for it, for now I'm trying to sell the trees I'm creating with the script, so if I distribute it, I'll reduce my chances
By the way, the script is not very user friendly and requires some tricks to achieve a result and I don't want to spend time to document it.
I'm trying to port it to blender 2.6 and maybe, one day I'll offer it ...

Hi Enrico, I have understood what happens with transparent shadows : it is not a problem with alpha shadows, but it is due to the fact that the mesh underneath the sticker has a material using the dirt texture : the dark area is dirt under the sticker !

A feature allowing the dirt texture generator to ignore faces supporting a transparent alpha would be very usefull to avoid this trouble.

Inverting the normal of the dirt and reducing all parameters of dirt to minimum can help a bit, but the dirt is very few noticeable... often not enough !

Thanks
