Looking great man!

 

On the ivyman you've got a bit of a crunchy alpha on the screen right door frame, it's only when it's lit up by the smoke so check the alpha you're using to stencil/mask your smoke/fog elements. Also check the camera you're using for the image in the bg behind the door frames, just after the smoke clears it jolts around a bit. 

 

I think as well that if the light source to the right was that bright, the ivyman would have a substantial rim light, so either tone the light down or add a rim light in there. One last thing would also be to bring the sky down a bit, it's looking a bit bright for how the inside is exposed.

 

Thanks Liam. Appreciate it.

 

 

 so

 

I was looking at a few tutorials online and I came across an awesome video by Hugo Guerra on the Reconcile 3D node. I thought I could use it to create fog lights for the car. this is just a proof of concept for now.

 

Password: fog

 

 

So the way I got this working without the alembic cache was to use the deep comp as reference for the axis node:

Here is the scene set up. I am using an expression in the XY from the reconcile node to drive the volume ray to create the volumetric fog light. all of this was done without the use of maya.

This is the result on the plate:

I am going to do something with this to make the comp more interesting I guess. Aiming for maybe a night shot.

Here is an update on the volume light, I managed to get the other headlight volume in and created an expression to orient the rotation of the second axis to the same as the first so I am matching the rotation of both axis for the Reconcile node but I am keeping the position different. I then used some stock footage to multiply on top of the volume to break the cg a bit more. The volume slips a bit but I am able to control the offset of the volume ray node with a transform node. It needs further refinement.

Also as an added bonus I may look into adding rain to the scene (MAYBE) I found a cool gizmo on nukepedia that uses a particle emitter to create rain on the lens, I can then use a voxel to either emulate the rain or place some rain stock footage on top for the volume light to cast through. Goal is to make the scene a night time shot.

 

Here is where I got the node:

nice idea with the reconcile3D node for headlights, with some fine tuning it could look pretty sweet, but as you said you'll have to make your shot seem like evening or night to pull it off.

 

and yeah rainmaker is a pretty nice tool, you'll want to precomp your output from it once you get a look that you like though rather than having it processing live because it's super heavy and will turn your nuke script into this:

I would say its unlikely you will get that mini scene to register as night, especially in the rain. A ton of reflections and wet look would need to be added. The sky would need completely replacing to look even half decent. The car will need ro rendeirng under different lighting conditions if you wanna fool anyone who understands how light works. I would be pretty sure the best you will get is a slightly dodgy day to night conversion, I have rarely seen those look good! Give it a go for sure if you wanna experiment but don't fall into the trap of horrifically over comping things, it looks odd very fast when somehting is pushed too far in the comp stage.

 

Volumetric thing is cool!

I get what you mean. really this is for me to try out just so I can learn something new from it. Most of our feedback is that there is never really anything interesting to show with the mini and the Ivy man, they all are pretty much the same. Me personally I don't want to be doing the same thing that 100 other students are doing and have done in the past. Its all experimentation and I am fully aware of what other factors come into it. I am just trying to go beyond what is shown in class and I do appreciate your input. Plus if it looks bad in the end I have another comp to show that can be graded. For now I am trying to just do something different with what I have in hopes I learn from it. Thinking realistically the rain wouldnt be worth the effort, so I agree. Plus there is not that much creative freedom comp wise this semester. :)

Here is the mini with the day to night conversion, again this is mainly just for practice/learning from, if I can I will submit an updated version of this along with an updated version of the other mini comped at day. I did a few things like adding stars to the sky by projecting onto a sphere and multiplying the image onto the plate whilst using an alpha for the sky I made with a luminance keyer. I also tried removing some of the brighter highlights from the reflections in the plate as well as adding a light from a window. I am most likely going to cut that out because its drawing too much focus away from the actual mini and the lighting is hard to match. I added a rim light to the mini by the window but due to the difference in lighting it isn't working the same way it would in real life so that is another reason I am going to remove the lit window. This is all just me testing what is possible to do with what I have.  :ph34r:

I need to add more bounce light from the headlights as well as probably toning down the beams. it also needs to cast more light to the surrounding area and floor. That is one of the things on the list to update.

Comp in a street light and get some rim lights going FTW :)

Its been a while since I have touched this thread, here is the VFX specialist submission from earlier today. I am hoping in updating this thread more over the next few weeks with some cool stuff (that is debatable).

not sure how you are getting the jointlist, but it would be better to have a function to get this, then you wont have to declare the list as a global variable which is generally bad practice

 

something like:

This is how i'd do it personally as it makes bits of code reusable 

import maya.cmds as cmds

def getJointList():
	# get starting joint
	startjoint = mc.ls(sl=1, typ='joint')[0]
	# list children of start joint of type joint
	jointlist = cmds.listRelatives(startjoint, c=1, ad=1, typ='joint')[::-1]
	jointlist.insert(0,startjoint) # insert start joint at start of jointlist
	
	return jointlist
	
	
def createSplineIK():
	
	# get joint list
	jointlist = getJointList()
	
	#### rest of code ####

Hey man, I did notice some weird warping on your trees in the first jack and josh shot. I could be wrong but did you use an iDistort or grid warp? other than that looking good. :)

Cheers Dan, scripting this year was a bit of a mess, it wasn't the fault of anyone. we all handed in the same script as a part of this submission, for a future reel I am going to use something I make myself. I appreciate the input that actually makes more sense in comparison to what we were shown in class, thanks

It was a mix of the two, I can see whats happening. Damn, I actually didn't notice that. Appreciate the feedback :)

Thanks, I am still working on improvements to it.

Have not really touched the lighting in a while, please excuse the poorly animated sequence. As you can see animation is not my forte. Here is what I got:

This is what it looked like before I nuked it:

Looking good! the only thing i'd say is the original has a much greener overall colour to it, not sure if they'll have done this with lights or in post, but you could definitely just gain up the greens in a colour correct and i'm sure you could get a similar effect!
Great job getting that light above the door to fall correct though, really matches up!

Yep, You need a touch more yellow in your brighter areas and green in your midtones. Very nice lighting though! Matches pretty well.
