ok first things first.
go to photoshop..delete the white on the tree so its transparent..
save as a png file
go to sketchup, and copy that image into sketchup. (drag it in)
youll see the white is gone.. (it will show in podium if you render)
now make it a symbol (component) (face me switched on)
after creating your tree... it will face you as you move around..
go into the symbol, make a copy of it ant rotate it to make a 30 dgree cross. close it... it just makes it look more fuller.
note it will not cast shadows.
to cast shadows.. you need to take thet tree texture and put it on a face...cut it out as close as possible and the cut outs will cast shadows..
goos luck )

I have been using this technique, minus the second tree plane, and it works great.  I have two questions though -

1. Does anyone know how to get ride of the white "halo" around the tree in podium render.

2.  Is there a way to make the tree not render in podium, but render the shadow so we can insert the tree later on in PP? 

Thanks - I have also posted this problem in the Main Area - my apologies for that.

if have a bit of photoshop skills, dont need to be a superhero in it lol, but you can take the tree out in sketchup if you dont have proper ones. if your angle is low, you can put it in via photoshop. the shadows. make another layer,magic want selection the tree, and dump a grey into the selection, make it transparent and transform it, rotate and position where it needs.
yes it is not the best, but at least you can have shadows, you can manipultate. you can slightly blur the shadow with the blur tool so that it is not that sharp.
I will try to get some proper tuturials how to do that, or how i did my tree park, still not perfect, but its a good start.
if you want to go the other way.. rendering trees, its gonna take looong.
until podium support png images for render, we just need to hang on.

Thank you for the great replies!!!  I was trying to get away from anything in post, but looks like for now I will have to keep grinding in photoshop.  I was experimenting with putting the tree transparent in SU, then rendering it so only the shadow would show up, but Podium will not render the shadow then.  Oh well, we shall wait....TBD please....pretty please some PNG support. 

Thx again Silvershadow!!

RickW is about to finish the ImageProfile Script, it will trace a PGN image, cut it out and create a component, you could look this site

Could the free content trees with the halo either be removed or updated then ?

We have an updated build of the render engine that we are currently testing that improves behaviour of transparent png masked images.

When we have tested this more throughly, we'll decide what to do about the trees.
It's a big task to re-mask them all!

I have posted a Photoshop masking tutorial here that you can use for trees, people or anything else.

[Edit: I have tested some of the auto-trimming scripts, and the ones I have tried, don't work well with Podium]

Sounds good, I just think the ones that are sub standard should be removed, it's a right pain in the ass to see your renders with a rubbish plant and pot in when the rest is great, a fly in the ointment so to speak.

Sure, but until we render these with the new engine, we won't know whether they are any better

I agree entirely with the principle though!

I know this is old but to remove the halo on png images,

from sketchup, edit your texture file, in this case the tree png file. I use photoshop. 
  • from the layers pull down menu click matting all the way at the bottom, defringe.
  • in the pop up window enter a value of 1 or 2. that's all you need.
  • click ok.
  • save.
  • your texture will update when you go back to sketchup. fixes 90% of halo problem.
or
  • if you edit your materials independently, you can update the image file for each texture file.
  • then, in sketchup, double click on texture file.
  • instead of opening to edit, click the pull down menu below the texture name and click load.
  • Screen Shot 2018-03-03 at 10.07.03 AM.png 
  • track your way back to your texture file.
  • save.
  • your texture will update when you go back to sketchup.

really complex edges or lower resolution files will be harder to fix. search my posts, my larger 2D trees are from the browser and look fine. I perform this procedure for most png files with an alpha transparent mask just to be sure. I've had pretty good luck with just about all the 2D plants from the browser. I haven't used them all, but I've used quite a few.

the little trees in this image are still showing a little halo. minus the cactus, everything else is 2D content from the browser.

all trees are 2D trees from the browser, minus the pine.
