Thanks... you've just saved me a heap of time.
Will let you know if any other issue pop up.
Thanks

Hi TIG
I have just noticed that the components created using the image trimmer cannot receive shadows even if the option to do so is checked under entity info....
This seems to happen when a png is applied to the surface unlike say a jpg which does receive them... i've tried this with material texures and people.
Any ideas?
Also I have just noticed that a component set to always face the camera cannot receive shadows either??? this happens in skp 7 & 8...
i have just never noticed till now... could this be a bug or is there some reason why this is the case...I'm trying to build up a library of people and realised this when they wouldn't cast shadows on each other...
This can make some exported images look a bit strange especially when you expect to see something in shadow and it kind of pops out at you.I appreciate any pearls of wisdom you might be able to offer on this.
Thanks
Dave

I never noticed that either.
A transparent PNG can't receive shadows !
However, a 'flattened' PNG [without transparency] or a JPG can...
Here's a fix - not ideal but it works...
Edit the component and with the eye-dropper pick its material in the Material Browser.
Edit that material.
[You need to have set you image-editor in Preferences - I use Gimp...]
It opens, save_as a JPG with the same name [note the folderit's usually in your own 'Temp' folder].
Now edit that material and change the texture to the JPG version...
Alternatively 'flatten' the PNG and save it.
NOW the material accepts shadows - since the image is trimmed to remove transparent its areas its 'PNGness is no longer useful - so a JPG works just fine !
I could automate that part in ImageTrimmer - I'm thinkings about it overnight...
The additional steps are that when the material is made with the PNG texture we have already exported it as a PNG file into the temp folder... so we simply convert that PNG file into a JPG/flattened-PNG file and we have an option to use that as the new material's image instead of the PNG...EDIT: option to flatten the png now added to v1.9...
-
Here's a link to get v1.9 http://forums.sketchucation.com/viewtopic.php?p=293677#p293677
There is an added option to 'flatten' the new material's texture PNG [i.e. remove its transparency] so that the material will then receive shadows.
Feedback please...

Hi TIG
Sorry for the delay in feedback...chaos at work so I didn't have time to 'experiment'.... Anyway... here's what's happening now...
If I choose the flatten image option, it does flatten it (evident by a flattened image in the trimmed files folder) but does not substitute the texture in the sketchup material for me. I have to sample the material and reselect the flattened image file manually via the material pallette. This is fine if you are opting to keep a copy of the trimmed files but is not if you choose to delete them...
I'm sure you were intending for this to happen automatically... ?
Otherwise despite this apparent hiccup, this plugin is fantastic!
Looking forward to the next version.
Cheers

DaveCan you run it with the Ruby Console open - it's working fine for me ???
Is this failing on PC and MAC ?
If you choose 'flatten' image it makes another png file in the TrimmedImages folder with [Flattened] in its name - that has no transparent pixels so it accepts shadows.
Then it uses that as the material's texture instead of the original one with transparency, scaled appropriately as before.
I can't see why it's working for me and not for you ?
Can you post the original transparent image png so I can test it
-
Here is a typical file that doesn't work on my side...
I suspect it is going to be something with the way it has been saved as a transparent png.
I am on PC.Thanks

Hi again TIG
Just tried again with ruby console open... 3 seperate images... no success.
This was the message:quietly_force_sync_mats_cb just calledquietly_force_sync_mats_cb just calledquietly_force_sync_mats_cb just calledquietly_force_sync_mats_cb just calledquietly_force_sync_mats_cb just calledquietly_force_sync_mats_cb just calledERROR: skpHelperClasses.rb:updateSkpMaterial, unable to find a material called: kid041

it then gets into a loop and keeps posting this...
I'm sure it means more to you than to me...

OK... so if its not the image itself then what about your external image editor...?
Which one do you have listed in your sketchup preferences? TIG mentioned his was Gimp... but I am using a Corel app...
Don't know if it will make any difference.
-
I don't know if it matters either. I don't have an image editor set in Preferences.
Out of curiosity, what happens if you download the image from your post and use it? Is it possible that something about it gets changed when it is uploaded to the forum?

DaveAll of those error messages are nothing to do with ImageTrimmer or raw Sketchup ??? What otehr tools do you have loaded that might manipulate materials in the background ? and thereby clash...
The external image editor doesn't matter...
-
Your image also works 'fine' for me... although it didn't flatten and use [Flattened].png version as expected ???
Seeking reason... -
TIG, I was prompted to "flatten" when I tried it. I wonder what is different.
-
I have the reason - sometimes the flattened image wasn't ready to apply when it tried ... but now it waits until it is - an update is in the pipeline
-
Aha... So thats why the ruby console sometimes took a bit longer to display the progress of the process than other times
I did get it working on ocassion but could quite pinpoint the cause when it failed. When it worked the ruby console was quick to report... when it didn't, the console seemed a bit sluggish.Great TIG... so i guess you have figured it out (hopefully)...
I'll wait for the update before trying again.Thanks

Here's a link to get v2.0 http://forums.sketchucation.com/viewtopic.php?p=293677#p293677
I have now sorted out the Flattened Image creation so that the new texture is not applied until it's 'fully-baked'. The earlier version sometimes jumped in too soon and the flattened-image file was 'half-baked' so it didn't get applied properly. It should now as it waits until it is 'fully-baked'...
Feedback please...
-
Fantastic! That seems to have sorted it...
I am still getting some mumble in the ruby console... This is a near to fresh install of SKP 8 so I don't have many plugins installed...
Hang on... I've got Vray for sketchup and its mentioning syncing of materials so maybe Vray is trying to catch up with the image swaps that your process is doing... If you're creating temp files whilst it happens, Vray might be looking for those when they've been deleted.... hmmm... for now its working just fine for what I need... and vray renders them out just fine too...
I will let you know if I discover anything else.
Thanks again for you help in resolving this.

'Simplified image' - a rare error on delete edge is now trapped.
Please get the new version from this link... -
Hello TIG,
I have been reading the whole thread, but I am still not sure, if you have finally been able to resolve the "mac glitches" with OXER.
On my Mac (Snow Leopard 1.6.6) ImageTrimmer gets stuck with an error message.
This is what I do:After importing and selecting the "test.png" I run ImageTrimmer.
The ruby creates a folder named TrimmedImages containing the selected image.
Also the two .ini files containing the following Pathnames:/Users/kai/Desktop/TrimmedImages/test.png
/Users/kai/Desktop/TrimmedImages/testThe Ruby Console produces an error message (see first screenshot)
On double-clicking edgeDetector.jar in the SKMtools folder two more files are generated in the TrimmedImages folder:
testEdges].dat
test[Edges].png
the .dat file containing zeros and ones, and the second .png showing the desired contour (second and third screenshot)############################################################################################
Since this is my first post on this forum I don't want it to lack my appreciation for all of the plugin writers, whose contributions I have been so shamelessly enjoying over the past years. Thanks a lot to all of you!!!
