Homework submission – week 2 – Tree A FG (texture baking)

@jlampel  @theluthier ,  still working on the leaves…

Hi Kent,

I really liked what you showed in the demo yesterday,  so I downloaded the file and played a bit with the material you created.
I incorporated it with the instant collection i have created before, and i think the result came out realy nice,

tell me what think please…

(I have uploaded the file to the Drive)

Wow, great work on that trunk and on those leaves! I’m checking out the file now and it looks *gorgeous*. 

We do still need to refrain from using any emission, since keeping shadows consistent throughout all the assets will be super important. 

Using some SSS was a great idea. I like it! Turning on Subsurface Translucency in the material helps even more. 

I would recommend adding some specular back in, since that helps give it shape. 

Mixing in some translucency like this also helps to make it more painterly:

Lastly, even though the vertex count is pretty low thanks to instanced collections, the amount of transparent planes makes the compiling take a bit longer than is probably necessary. See if the middle of each clump can be an opaque sphere of leaves and delete all the planes inside of it to help this render faster:

Keep up the good work!

Edit: Oh, and I do still think that the scale of the leaves is a bit off. I think the size of the clumps you have is perfect, but in terms of the leaves themselves, something like this would work much better:

Thank you Jonathan!!!

@jlampel , will start working on all your comments

[Dani Tufeld]

Hi Jonathan,

@jlampel 

I have tried adjusting the shader according to yours comments:
I removed the emmision completly, and scaled down the size of the leaf.
Reagading the clump in the middle, if the geomtry is good cause of the intant collection, would it work if I switched back to a leaf shape ngon instead of using a quad plane with alpha? would it be more efficient?

I have uploaded the new file

Another test with several leaves panited on each plane, 

80 particles insted of 200

[Matthew Ullrey]

@danitufi That second render with the 80 particles is looking really nice! I like I like! 🤩

 Homework submission – week 3 – Tree A FG (texture baking)

ו submitted last week, meant to write week 3!

@jlampel  @theluthier 

[Jonathan Lampel]

if the geomtry is good cause of the intant collection, would it work if I switched back to a leaf shape ngon instead of using a quad plane with alpha? would it be more efficient?

Even with instancing, it appears that the render time is much lower overall if all the plants use planes with alpha instead of leaf shaped geometry.  One tree by itself might be faster with geometry, but with the number of plants we’re supporting in one scene we need to go with image planes. 

I agree with Matthew – that second render is looking NICE! The only thing that sticks out to me is that I think the SSS is a bit more extreme with less geometry and is a bit overpowering in that one. I would also enjoy seeing some small branches connecting those leaves so that some aren’t floating off in space. A color map to go along with the alpha map would allow you to add those in as well as add some color variation and detail to each leaf without the need to do it procedurally. 

Top notch work here, and full points for week 3!

I wanted to reiterate what I said during the stream when I integrated you tree: You did an amazing job! Your tree looks fantastic in the assembly.

Thanks for joining Collab2021! It’s been a pleasure working with you @danitufi 🤝

[Dani Tufeld]

Thank you @theluthier for an amazing project, had so much fun!!

Thanks @jlampel for the great tips that made me go diper in to practice and research!!

and all the CG Cookie community that was involved!!

It was awsome!!!!
