Hi,

Here is the first image of a new serie, I'll update this thread with the new images, many to come I think as this scene is quite complex, and in varius lighting and seasons ...

I saw that house in the december Bati Deco magazine (Architect is Anthony Duffeleer) and I took some liberty with the model but it is very similar.

Except the very far trees made with an image on a plane, everything is 3D and home made, thanks Octane to provide such result with about 1.1 gb of memory.

Edit : Some answers to various questions

For the vegetation I try to avoid geometry and I make big use of planes and opacity maps for plants and leaves. For grass, this time I just used a high definition grass map and used subdivision and displacement for the foreground part and reduce the subdivision until the background grass with no subdiv and no displace, the result is not bad at all since I have those plants on foreground.

For trees, I'm still using some home made tools which help me to generate them, I usually make the leaf maps myself and groups several leaves in a single map to reduce the textures amount. To improve the result I should give them some translucency.

Rendering time was about 1h in 1800x1000
Lit with an hdr map
About 4.2 million polys

For this one I used a RGB spectrum on the transmission channel for leaves to get some translucency
Rendering time was about 3h in 1600x890
Lit with an hdr map
About 4.2 million polys



Here is an interior shot with several mesh lights
Rendering time was about 1h30 at 1400x850



An interior shot with several mesh lights
Rendering time was about 30min at 1600x1000

I added some more mesh lights, it increases the rendering time but not so much, about 2h for the two last images in 1600px wide. I used a spherical sky jpeg map, as it doesn't have any hdr channel, it doesn't illuminate the scene but it produces a diffuse light useful to give some tonality and some atmosphere to the scene. Using such a jpeg map produces few noises and reduces the rendering time.

Hrrr hrrrr...realy cool, again.
Your day has how much hours?

wow great

When you get a chance, would you please give a little more detail regarding how you are modeling some of the vegetation.

This is a fasinating project you have started. Beautifull work BTW.

Thanks for viewing,

nice start...good work..i look forward to the rest of this series..

btw..if you try daylighting (instead of hdri)- would you get proper shadows out of these leaves..? how would the scene look like then? I am just curious

thanks for sharing tips...appreciated

This is a really great scene!!!
My only comment is that the house looks a bit smaller than it should... Maybe this is caused by the camera position and angle, but I think that even the grass is bigger than usual, compared to the house...
Other than that, bravo!

Hi,

@suhail_spa:Indeed, with the current release using daylight will produce some strange shadows and though I avoid to use it in such views.

@JJTTBB:I tried to take care about the proportions which should be more or less ok, indeed this is probably due to the camera as I use a big angle.

I udpated the thread with a new image and this time I tried to get some translucency on the leaves using a RGB spectrum on the transmission channel.

this is what i miss the most in octane..hope its resolved in next release..
AND we should have option of changing background while using daylight...
sometimes i have the prefect sky color but not shadows where i want them- and vice versa...
HDRI is never enough to give good image especially in architectural views -as we DO need shadows with contrast to highlight what we want to...though hdri offers a good backdrop ... (i dont want to rant what has already been discussed by many before.. )
thanks for your reply...
