Anyone know how to set/change the Transition Curve from Linear to Step for example from Python.
I can see it in the Class list but no idea how to set it?

def RLPy.RKey.SetTransitionType	(	self,
		eTransitionType
	)

Is it a number a string?

Regards
Chris.

Thanks The-any-Key
will check those out shortly.

I am trying to change the step of a matieral from Linier to Step but having no luck yet, this is a cut down piece of code I am using.

import RLPy

#-- Get Prop --#
prop = RLPy.RScene.FindObject(RLPy.EObjectType_Prop, "Ball_000")

#-- Get Material from Prop --#
material_component = prop.GetMaterialComponent()
mesh_list = prop.GetMeshNames()
mesh_name = mesh_list[0]

material_list = material_component.GetMaterialNames(mesh_name)
material_colour = material_list[0]

#-- Add diffuse key --#
material_component.AddDiffuseKey(RLPy.RTime(0), mesh_name, material_colour, RLPy.RRgb.RED) # Turn on Red
material_component.AddDiffuseKey(RLPy.RTime(1000), mesh_name, material_colour, RLPy.RRgb.BLUE) # Turn on Blue

# How to change the material keys from Linier to step ????
# This is not working????
#material_component.SetTransitionType(RLPy.RTime(0), RLPy.ETransitionType_Step, 1.0)

RLPy.RGlobal.Play(RLPy.RTime(0), RLPy.RTime(1000))

This will change a default ball "Ball_000" from red to blue and as you can see it it changes over the one second run (linier) this is what I am trying to change so it will change suddenly "Step".

By the way this is from a "Traffic Light" setup I am working on so really need this change to make it work.

Regards
Chris.

Try

material_component.SetTransitionType(RLPy.RTime(1000), RLPy.ETransitionType_Step, 1.0)

By The-any-Key - 5 Years Ago

You need to get the key object you want to change.
Ex:


# Grab transform control from prop
transform = prop.GetControl("Transform")
# Create empty key
key = RLPy.RTransformKey()
# Fill empty key with data at time 0 from prop
transform.GetTransformKey(RLPy.RTime(0), key)
# Set transition for key to step
key.SetTransitionType(RLPy.ETransitionType_Step)

I am however unsure if the key object is referencing back to the original key data. Or if you need to add the key to the prop. But we hope it use referencing.

Thanks dogged2003 but that will not work

That will run without error but it will not change the material settings?
I will look more closley at the documention tonight and try to see why I cannot seem to access the Material Settings to change (unless these are not avaliable yet)

I have of course tried many different ways to try and get this to work but so far without success, keep getting an "Atribute Error"

Many Thanks
Chris.

Chris,

There's a confirmed bug (confirmed by the devs) in GetMeshNames so that GetMaterialNames will not work properly (fails). If that's your problem don't worry about it -- should be fixed soon.

Set to one of these I think:


RLPy.ETransitionType_Linear
RLPy.ETransitionType_Step
YourKey.SetTransitionType(RLPy.ETransitionType_Step)
etc. etc.

Hi,
pls, where did you find these definitions in the doc ?
I might have missed, but I could not find any of the values in the API doc.

Thanks

Roberto

No docs. I check the source code of the wrapper in iClone 7>Bin64>RLPy.py

Tips is to request a sample how to do it in https://forum.reallusion.com/399188/Basic-Samples-Request-thread

Thanks!

Thanks for the tip done.

Just continued with the samples and found this:


# Grab transform control from prop
transform = prop.GetControl("Transform")
# Set key transition in frame 0 for prop
transform.SetKeyTransition(RLPy.RTime(0), RLPy.ETransitionType_Step, 1.0)

This is however for the transform keys, not the material keys. So the material keys might not have been added to the API in the way so you can change the transition type.

That was the first one I tried but it did not work, will assume as others have said the material settings are still in experimental mode so not avaliable at the moment will wait and see after the next update.

Will place on feedback tracker so RL ia aware of this issue.

Have placed on feedback tracker so hopfully not long to wait to get this functionallity.

Sorry, we don't have material "SetTransitionType" API yet.
