Landscaping

Hi all,

I am working on an exterior scene, that will have loads of trees, grass and other plants. These are my initial steps with Corona, so apologies in advance if some of my questions are too noob.

Any feedback is welcome

Grass tests with a new material


Getting there

Hi all,

Just wondering if this is a Corona problem or a 3D model problem. In the reflection setting if I use:

Translucency 0.5
Reflection Level 1
Reflection Color 200
IOR 1.5
Glossiness 1

I get the result shown in the Glo_1 (it is the Reflection pass)

But if change the Glossiness to 0.8 or lower I start to see some white points in the render and if I use the value of 0.5 I get the result shown in the Glo_0.5.

Am I missing something here? Any help is appreciated.


Thank you Rawalanche. Initially I thought it was a reflection artifact, but after testing the scene with a sphere as you recommended I could understand how the glossiness affects the reflections. Don’t know why I got stuck with the 0.5 value because a lower value actually resolves the problem and produces a better result.

I will upload some results today.

Thanks

A test with trees.

More trees. I found that Corona A7 handles quite well the heavy vegetation. Although the initial pass is quick, parsing the scene in this case can take up to 15minutes.

Any feedback is welcome.

such thing got reported multiple times and it was always not enough RAM, so check that first

I have 16GB of RAM. The trees are quite heavy with geometry maybe it is the reason why it takes so long?

By the way Keymaster. I love the fact that when I use full mesh for the proxy we can see the textures applied. Great upgrade.

I don’t use the full mesh in the preview, only wire-box. I just checked again and for this scene it takes:

Scene parsing: 17:02 min
Geometry: 8:04 min

Now is doing the initial pass and in the Memory I am using 13.3GB to render. With my personal pc it takes less time, but is because the computer is more powerful than this workstation (HP Z30).

is your total memory usage at or near the RAM capacity? (you will see it in task manager → performance tab)

From the Performance tab:

Physical Memory (MB)
Total 16179
Available 173

And the graph shows that I am using 15.5GB

:smiley:

Thanks for the help

ok, so it is slow because you run out of memory.

So the problem is the amount of geometry (proxies) that I have? Is that the reason why it takes so long to parsing the scene? I am using the default settings with a HDRI.

OMG try to use multi scater or at least corona proxies, i have 20-25 sec parsing in scenes with 1500+M polys.

And im also running on the 16 gigs of RAM.

I am using Corona proxies and Corona scatter. :\

Correction:

I am not using the default settings. I am using Path Tracing + Path Tracing.

Obiusly problem is not in the render settings.

Are you scattering grass with patches or with single models?

Single models. But they worked fine before adding the trees. It was when I started adding trees that things start to get slower. I am testing a new scene with the same trees and I am getting 5 seconds to parsing the scene. I am merging the trees one by one.

Try to colapse each tree in to single edit poly. And disable cache in RAM function in corona proxie settings. Also it si better to use lager patches of grass instead of single models yes it is harder to control but it works out well.

I always use evermotions treees and grass in my works only with some ajustments in the textures like opacity maps wich are totaly fucked up in evermotions originals.

The thing I don’t like by using patches of grass it is because it creates a grass that looks like a carpet. Probably is my fault of not using the correct settings. So far I merged all the trees in the new scene and works like a charm.
I am going to try to merge the grass and then test what you suggested.
