Chocofur IES lights for Cycles

Hey everyone,
I thought you might be interested in this one – I’ve recently uploaded 10 IES profiles created directly in Cycles using a node setup allowing you to adjust their look without any external applications. There’s also a Chocofur tutorial explaining the entire process and some issues you may come across when working with spot lamps in Blender.
Happy Blending!
This is fantastic. And the fact that they are made using nodes is even better. I’d love to see full support of IES lights in Blender by default. But this is a great start.
How does this differ from the IES addon that’s been about for a while, AFAIK that’s also node controlled, supports standard Ies files etc.
First of all – the addon imports IES profiles as Spot Lamps which causes issues with mixed scene illumination methods (ie. unnecessary noise when using HDR map as environment). Second – the node setup is much more complex and for some IES profiles it didn’t allow editing their power and temperature (except of re-importing them to the scene with changed values). Third – in order to change shadow softness you’d need to re-edit the IES profile itself – in our method you just scale up/down the mesh object emitting the light. And the last one – you don’t need any external addons. Just do it yourself in a few minutes using basic node setups.
Awesome, thankyou for the reply. Sounds very good, will have to give it a look. I always found the old plugin a little on the fidderly side, will be interesting to see the difference.
Ok, so I got around to trying these out and I’m very impressed, such a simple implementation and it works great. Thanks a lot for this.
The tutorial is awesome to product own IES lights, indeed. However I couldn’t use your IES.blend file as an IES light. Link/Append did not work. So how to use it for our already working scenes?
Thanks
Hey, you simply need to append an object with applied IES shader. They’re named accordingly and match the look of 10 reference IES lamps seen in the tutorial.
ugh… :D I have solved it Lechu thanks.
The problem was on that appending your great IES light object which goes to anywhere in scene. Then I could not see where lit appears. Find them in outliner and then grab to center in scene. So I advice to other users that firstly find apended IES-Light object where it is placed then use it in your scene’s absolute position.
euh?
