You will see the truth of the situation.
We have replied repeatedly, and have basically given up trying to explain the truth.
Some people just will not listen.
And LightSpace HTL is nowhere near a thousand bucks...
Where do you get that figure from?
If you are so confident that the product is usable with madVR, why not offer a time limited free trial to
? I just see on the website that you are offering free 3-day Lightspace licenses. Any reason why you are not willing to extend this offer to
? Hopefully in 3 days he should be able to see if the software is working for him or not?
I have posted this information in public forums because Light Illusion has repeatedly refused to fix these issues, and I think people should know about these bugs, shortcomings and quirks with madVR before buying the product.
Light Illusion as an uncanny ability to not read posts. Two examples (and I'm convinced that in your next reply you will still not have read my post below):
is considering Lightspace for his Discus. Is there a license that provides Discus support for significantly less than $1000?
2) You keep insinuating that I'm incompetent and don't understand the need for various video filters in Lightspace. I completely understand that need. What I disagree with are the reasons, and what to do about it.
a) The reasons are because Lightspace, unlike other software, generates by default LUTs that are not compatible with madVR. They do not follow the madVR specs, which requires video level LUTs. There is no issue in madVR. Every software that follows the specs and creates LUTs for madVR that use video levels have no issue. Lightspace doesn't. This is why it is needed to apply a filter on each and every LUT generated, for most users.
b) Given that Light Illusion doesn't seem to be willing or able to fix this bug, i.e. to generate LUTs for madVR that follow the madVR specs, the least they could do would be to allow the user to specify once and for all which filter needs to be applied, so that it's applied automatically by Lightspace to each LUT. For each user, the filter will remain the same as long as they don't change their video chain. Unfortunately, Lightspace doesn't support madVR specifically, so it's up to the user to make each LUT generated compatible, by applying manually the same filter, every single time. Saying that you need to provide the "flexibility" of choosing between five different filters might be valid for pro calibrators who calibrate a different chain each time, but it's not valid to an end user calibrating their own system. So this inability to specify which filter we want to apply is adding insult to injury: not only there is a bug in Lightspace not present in other software following the madVR specs, but there is no will from Light Illusion to make the process easier by adding a simple option so that the relevant filter, different for each user but the same in each session if the user calibrates their own system, can be specified.
I have no idea why, instead of processing the above information, and either agreeing that it's not ideal from a user interface point of view or finding a way to improve it, you prefer to insinuate that the person making the comment is incompetent and doesn't understand the "workflow" or why filters need to be applied when LUTs with the wrong levels are generated. The vague and daunting madVR documentation about filters was put together after I reported this issue to you. Before that, Light Illusion had no idea that a filter had to be applied to make the LUT compatible, so I suppose many madVR users were just happily using invalid LUTs (and possibly still are).
I haven't seen any reply from you or anyone else in any of the threads where I reported these issues offering a simpler workflow, or explaining what I was doing wrong. If I have missed it, please feel free to point us to such a solution, if it exists.
Like many, my chain is as follows: GPU Full, madVR Limited, display limited. So I'm using video levels through the whole chain and my levels are 100% correct. Both [typo corected] DisplayCAL (which, unfortunately, doesn't support the Discus) and Calman support this configuration automatically. I specify video levels in both software, and they generate a 3D LUT that is valid, every single time. They also upload the LUT automatically to madVR, while Lightspace requires another manual step.
If you fail to see why this is preferable for the user to the ten steps or so for each LUT required by Lightspace, then there is little to add.
Frankly, I don't understand why you keep this off-topic conversation going. If you're confident in the software, give a free 3-day Lightspace license to
, and let him report how he gets on with his Discus in this thread. That would be the simplest and easiest way to settle the matter.
I'd love to hear what an impartial user would say after having three days to try to get results from the product with his Discus and madVR.
If you don't agree to this, I'll let readers to guess why that is so, when Light Illusion are currently advertising free 3-day licenses on their website.
As far as I'm concerned, I'm off. Please refrain from another personal attack, I won't reply but will report the post.
